City of Huntington Beach Sewer System Management Plan 6

EXECUTIVE SUMMARY
Background
On May 2, 2006, the State Water Board adopted Water Quality Order 2006-0003-DWQ, Statewide Waste Discharge Requirements (WDR) for Sanitary Sewer Systems (Order) which required that every public agency in California with more than one (1) mile of sanitary sewers that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to prepare a Sewer System Management Plan (SSMP) outlining the management, operation, and maintenance practices needed to prevent and mitigate the impact of sanitary sewer overflows (SSOs).

Public agencies that meet this criteria are required to develop a system-specific SSMP per the provisions set forth in the WDR and comply with Monitoring and Reporting Program (MRP) attached therein.

A copy of the Order, along with the Amended MRP for Sanitary Sewer Overflows, MRP Order WQ 2013-0058-EXEC (Amended MRP), is included in Appendix A.

City Service Area and Sewer System
The City of Huntington Beach (City) is a coastal city in Orange County covering approximately 28.33 square miles. According to the United States Census Bureau, the City holds an estimated population of 199,223 residents as of July 1, 2019. The City’s wastewater collection system consists of approximately 360 miles of City-owned sewer lines and 27 sewer lift stations, which transport a combined, estimated

20.3 million gallons of wastewater per day. Regarding service laterals, the City is responsible for the maintenance and repair of the lower portion of the service laterals located within the City public right-of- way from the property line to the connection at the City’s sewer main.

Purpose and Need
The purpose of the City’s SSMP is to document system-specific activities utilized by the City to effectively operate, maintain, and manage its wastewater collection system to reduce the number and frequency of SSOs. This approach will in turn decrease the risk to human health and environment caused by SSOs. The SSMP includes provisions for proper and efficient management, operation, and maintenance, while also taking into consideration risk management and cost benefit analysis. The SSMP also contains a SSO response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions.

Organization of the SSMP
The structure of this document follows the section numbering and nomenclature specified in the WDR.

The SSMP includes eleven elements as listed below:
i. Goals
ii. Organization
iii. Legal Authority
iv. Operations and Maintenance Program
v. Design and Performance Provisions
vi. Overflow Emergency Response Plan
vii. Fats, Oils and Grease (FOG) Control Program
viii. System Evaluation and Capacity Assurance Plan
ix. Monitoring, Measurement, and Program Modifications
City of Huntington Beach Sewer System Management Plan 7 x. SSMP Program Audits
xi. Communication Program
About the SSMP
The SSMP serves as the City’s guidance document to ensure compliance with the various provisions of the Order and provides references to supporting documentation. Appendices within the SSMP contain reference information and support materials. Due to physical constraints, some references, i.e. large format drawings, relational databases, voluminous documents, etc., are not physically included in the SSMP. In these instances, documents links and references have been provided within the SSMP to indicate the type, owner, and location of the reference and support material.

The City’s first SSMP was completed and certified by the City Council in 2005, with an update to the SSMP conducted in 2009. This document constitutes the latest update to the SSMP and reflects current information on the City’s sewer system management, operation, and maintenance programs.

Per the requirements of the Order, this SSMP was developed by technically qualified and experience personnel. Update of this SSMP has been conducted by the City of Huntington Beach Department of Public Works per the requirements of the Order and the Amended MRP.

City of Huntington Beach Sewer System Management Plan 8

PROHIBITIONS AND PROVISIONS
Prohibitions
(In accordance with Section C of the Order)

1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited.

2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited.

Provisions
(In accordance with Section D of the Order)

1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action.

2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be:
i. Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order of Consent Decree;
ii. Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code; iii. Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for sanitary sewer system, authorized under the Clean Water Act or California Water Code; or
iv. Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board.

3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO.

4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains, flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains.

5. All SSOs must be reported in accordance with Section G of the general WDRs.

City of Huntington Beach Sewer System Management Plan 9 i. The Enrollee has complied with the requirements of this Order, including requirements for reporting, developing and implementing a SSMP;
ii. The Enrollee can identify the cause or likely cause of the discharge event; iii. There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration (I&I), use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems. iv. The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee;
v. The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for:
• Proper management, operation and maintenance;
• Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, I&I, etc.); • Preventive maintenance (including cleaning and FOG control); • Installation of adequate backup equipment; and
• I&I prevention and control to the extent practicable. vi. The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs. vii. The enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible.

7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water.

The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan including the following:
i. Interception and rerouting of untreated or partially treated wastewater lows around the wastewater line failure;
ii. Vacuum truck recovery of sanitary sewer overflows and wash down water; iii. Cleanup of debris at the overflow site;
iv. System modifications to prevent another SSO at the same location; v. Adequate sampling to determine the nature and impact of the release; and vi. Adequate public notification to protect the public from exposure to the SSO.

City of Huntington Beach Sewer System Management Plan 10

8. The Enrollee shall properly manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills and abilities.

9. The Enrollee shall allocate adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures. These procedures must be in compliance with applicable laws and regulations and comply with generally acceptable accounting practices.

10. The Enrollee shall provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the Enrollee’s System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system owned or operated by the Enrollee.

11. The Enrollee shall develop and implement a written Sewer System Management Plan (SSMP) and make it available to the State and/or Regional Water Board upon request. A copy of this document must be publicly available at the Enrollee’s office and/or available on the Internet. This SSMP must be approved by the Enrollee’s governing board at a public meeting.

12. In accordance with the California Business and Professions Code sections 6735, 7835, and 7835.1 all engineering and geologic evaluations and judgments shall be performed by or under the direction of a registered professional, competent and proficient in the fields pertinent to the required activities.

Specific elements of the SSMP that require professional evaluation and judgments shall be prepared by or under the direction of appropriately qualified professionals, and shall bear the professionals signature and stamp.

13. The mandatory elements of the SSMP are specified below. However, if the Enrollee believes that any element of this section is not appropriate or applicable to the Enrollee’s sanitary sewer system, the SSMP program does not need to address that element. The Enrollee must justify why that element is not applicable. The SSMP must be approved by the deadline listed in the SSMP Time Schedule below.

City of Huntington Beach Sewer System Management Plan 12 SECTION 1 – GOALS
This chapter describes the goals of the Sewer System Management Plan (SSMP).

The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system. That will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur.

Purpose and Need
The City is required to comply with Order No. 2006-0030-DWQ on General Waste Discharge Requirements, the 2013 Amended MRP, and any future amendments for publicly owned sewage collection agencies having more than one (1) mile of collection pipelines.

The goal of the SSMP is to serve as a guidance document for City staff. It provides a documented plan that describes all wastewater collection activities and programs employed by the City to ensure proper management of all wastewater collection system assets. Implementing the SSMP helps reduce and prevent SSOs, as well as mitigate any SSOs that do occur, including meeting all applicable regulatory notification and reporting requirements.

Goals
As a living and sustainable document, the SSMP is regularly reviewed and updated to address any changes to the City’s needs. The City’s current SSMP goals are as follows:
a. Protect public health and the environment through proper management, operations, and maintenance of all portions of the City’s wastewater collection system; b. Provide needs-based maintenance, including line cleaning, closed-circuit television (CCTV) inspection and evaluation, sewer lift station maintenance, and repair, replacement, and rehabilitation of the City’s entire sanitary sewer system to prevent, reduce, or eliminate preventable SSOs.

At a minimum, the City shall clean all of its sewer pipelines every two (2) years, and annually review its operation and maintenance practices and procedures; c. Maintain a CCTV Inspection Program to assess maintenance effectiveness and identify system deficiencies. CCTV re-inspections of the entire wastewater collection system, including manholes, shall be performed a minimum of every 5-10 years (10-20% per year).

CCTV re-inspection videos are to replace current system inspection videos. Spot CCTV inspections will be conducted during line cleaning operations to ensure line cleaning quality. d. Respond to and mitigate all SSOs discharging from the City’s sanitary sewer system and provide accurate reporting of all SSOs as described by the Order and the Amended MRP; e. Properly fund, manage, operate, and maintain the City’s sanitary sewer system with adequately trained staff and/or contractors. Maintain adequate reserves for future sanitary sewer system rehabilitation and/or replacement. Periodically review the City’s Sewer Service Fee to ensure that the fee is adequate to fund the need of the City’s sanitary sewer system.

City of Huntington Beach Sewer System Management Plan 13 Also included are the following specific goals:
a. Incorporate Standard Plans and Specifications for the development of privately owned sewer lift stations that discharge into the City’s wastewater collection system; b. Continue to improve the ability to provide real time monitoring to the City’s collection system.

The first step in this process is to capture data from the City’s existing facilities by monitoring wastewater flow at key locations, such as sanitary sewer lift stations and select manholes; c. Regularly obtain flow data from the Orange County Sanitation District (OC San), for sewers downstream of Huntington Beach, in order to capture and trend overall sewage flows coming from the City; and
d. Update the City’s Sewer Master Plan every ten (10) years to review for capacity for new developments, and changes in industry standards for design and operating capacity.

City of Huntington Beach Sewer System Management Plan 18 Organization Chart

City of Huntington Beach Sewer System Management Plan 19 SECTION 3 – LEGAL AUTHORITY
This chapter describes the legal authority required to implement the SSMP plans and procedures.

Each Enrollee must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the legal authority to:
a. Prevent illicit discharges into its sanitary sewer system (examples may include I/I, storm water, chemical dumping, unauthorized debris and cut roots, etc.); b. Require that sewers and connections be properly designed and constructed; c. Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency;
d. Limit the discharge of fats, oils, and grease and other debris that may cause blockages; and e. Enforce any violation of its sewer ordinances.

Prevention of illicit discharges
Resolution No. 2003-52 adopted the City’s 2003 Sewer Master Plan, which includes an analysis of the need for replacement of existing sewer facilities and construction of new facilities needed to serve new development and additional capacity demands. To deal with the uncertainty of future development at the time, extra pipeline capacity was added to allow for the possibility of actual wastewater flows being slightly higher than anticipated flows. The Sewer Master Plan also included probable locations of I&I to assist with future CIP project planning. Additionally, the pipe capacity criteria therein reserved a portion of the capacity for I&I, ventilation, and hydraulic instability.

Municipal Code 14.36.030 requires submission of plans and specifications for new sewer mains and/or connections for approval by the Director of Public Works. As part of said approval, any new illicit connections are prohibited. Municipal Code 14.25.030, as well as Section 306.0 – 306.2 of the Uniform Plumbing Code, as adopted by Municipal Code 17.44, prohibits discharge of inflow other than sewage, which includes existing illicit connections.

It should be noted that the City storm water infrastructure has low flow diversions (LFD) at most of its flood control stations. These LFDs are not considered illicit connections. A LFD is a structural system that diverts urban dry weather flow into the wastewater system for the purpose or reducing pollution in the ocean. Flow is only diverted during non-peak wastewater flow periods and is monitored and remotely controlled via supervisory control and data acquisition (SCADA) systems at each flood control station to ensure that the diverted stormwater flow remains within the wastewater collection systems operational capacity. In addition, LFDs are permitted by OC San to ensure regulatory and operational compliance with their wastewater collection system and wastewater treatment facility.

Require that sewers and connections be properly designed and constructed Municipal Code 14.44.020 requires submission of plans and specifications for new sewer mains or connections for approval by the Director of Public Works. In addition, Municipal Code 12.10 adopts the Standard Specifications for Public Works Construction together with adopted Standard Plans of the Department of Public Works, as well as the Uniform Plumbing Code, as adopted by Municipal Code

17.44, outline design criteria and construction methods.

City of Huntington Beach Sewer System Management Plan 20 Ensure access
The entire City’s wastewater collection system is already within the public right-of-way, on City-owned property, or within maintenance and access easements.

For new developments, Municipal Code 14.36.030 requires submission of plans and specifications for new sewer mains or connections for approval by the Director of Public Works. Conditions of approval are written to require that ingress/egress for maintenance of the sewer main and any connecting laterals is provided. Maintenance and access easements are conditioned as needed to ensure adequate access for maintenance and repair of all sewer infrastructure.

Regarding service laterals, the City took ownership of the portion of the sewer service laterals within the public right-of-way in 2008. As service laterals are repaired, replaced, and/or rehabilitated, clean-outs are being added at the public right-of-way as part of the Sewer Lateral Program to enhance and ensure access to all sewer service lateral connections.

Limit the discharge of fats, oils, and greases
In 2004, the City adopted Municipal Code 14.56, the Control and Regulation of Fats, Oils, & Grease (FOG Ordinance), and developed the FOG Control Program to address this element. Municipal Code

17.44 adopts the Uniform Plumbing Code, which requires the installation of a grease control device as required. Further, Section 306 of the Uniform Plumbing Code prohibits grease and other debris from entering the sewer system.

In 2013, the FOG ordinance was revised by City staff and adopted by City Council. The major revisions to the FOG ordinance include:
• FOG pre-treatment required for all existing FSEs that produce FOG upon change of ownership or change in operation which would involve the onsite cooking of beef, poultry, or fish; • FOG pre-treatment required for FSEs that undergo a remodel exceeding $50,000 in costs or involving one or a combination of the following:
o Under slab plumbing in the food processing area;
o 30% increase in the net public seating area;
o 30% increase in the kitchen area;
o Any changes in the size or type of food preparation equipment; • Clarification of language regarding employee training for FSEs in the FOG Control Inspection program. Revised ordinance requires existing employees to be trained at least once every six (6) months and all new-hires within two weeks of hire; and
• Require periodic maintenance of private sewer laterals to prevent blockages; no more than 25% of sewer lateral capacity can be impacted.

The FOG Control Program as coordinates with the Line Cleaning Program to add problematic FOG locations to the “Enhance Cleaning Locations” list to ensure more frequent cleaning of the sewer pipe at these problematic locations. Cleaning frequency is determined based on FOG severity at the location.

City of Huntington Beach Sewer System Management Plan 21 Enforce any violation of its sewer ordinances
As adopted, the FOG ordinance gives the authority to the inspector to cite FSE’s that are found to be in violation of the FOG ordinance. City staff also has the authority to issue enforcement actions for SSOs under the City’s Storm Water and Urban Runoff Management ordinance (Municipal Code Section 14.25).

Enforcement actions include Notice of Non-Compliance (formal written warning) that are issued for minor violations and Administrative Civil Citations, ranging from $125 to $1,000, that are issued for more severe or repeat violations. City staff also has the authority to issue Administrative Compliance Orders requiring the repair and/or replacement of private sewer laterals that are in poor condition due to structural deficiencies or lack of maintenance.

Compliance Documents
The aforementioned Municipal Codes are included in Appendix B, and can also be accessed on the City’s website at the following link:

General Information
The City of Huntington Beach is an urban city with a population of 199,223 residents, as of July 1, 2019 per the United States Census Bureau. The City encompasses approximately 17,730 acres, or 27.32 square miles, of which 97 percent is developed for residential, commercial, industrial, institutional, public, and street/highway use. Residential use is the largest single land use in the City. The City of Huntington Beach is surrounded by the City of Westminster to the north, the City of Fountain Valley to the northeast, the City of Costa Mesa to the east, the City of Newport Beach to the southeast, Sunset Beach to the northwest, and the Pacific Ocean to the west. Elevations vary from below sea level to approximately 200 feet above sea level.

The City owns, operates, and maintains a wastewater collection system consisting of 27 sewer lift stations, 360 miles of sewer pipelines, and 10,091 manholes. Pipe sizes range from 4 to 30 inches in diameter, and collectively transport approximately 20.3 million gallons of wastewater a day. The lift City of Huntington Beach Sewer System Management Plan 23 stations vary in capacity from approximately 80 to 1,800 gallons per minute, and assist in transporting roughly a third of the city’s wastewater. The remaining amount is conveyed via gravity flow.

Mapping
The requirement for this section is to maintain an up-to-date map of the sanitary sewer system showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and storm water conveyance facilities.

The City of Huntington Beach currently utilizes a Geographic Information System (GIS) based mapping system for its sanitary sewer system. The GIS database was developed to assist with compliance for GASB-34 requirements to inventory and assess the current value and depreciation of the sewer collection system.

At a minimum, the following information is continuously maintained within the City’s GIS Utilities database for all public sewer lines and sewer manholes:
a. Type of sewer pipe installed (e.g. vitrified clay, cast iron, etc.) b. Date of installation or replacement based on the date of record drawings c. Size of pipe (based on diameter in inches)
d. Manhole rim invert elevations
Detailed information is stored within the general description fields of the point and line elements of the Sewer GIS database as follows:

All wastewater collection system GIS database information is housed and maintained by the Public Works GIS Section, who are overseen by the Utilities Technology Coordinator. The City’s wastewater collection system maps accurately reflect pipe locations and are useful tools for planning maintenance activities. The maps are checked by line cleaning crews as they are being used with any changes coordinated with GIS personnel and updated as needed. All updated information is submitted to the GIS section for correction on all future printed maps.

In addition to the electronic database, the GIS Section also maintains up-to-date hardcopy map books for reference by maintenance field personnel. Copies of these hardcopy maps are also distributed to various departments citywide. Tract As-Built maps showing both the sanitary sewer system and storm drain systems are stored via document imaging with hardcopies housed in the Engineering Division of the Public Works Department for the City. The maps include the locations of manholes and their ID tags, siphons, easements, property parcels, pipelines, their depth and direction of flow, and other details. The GIS section also creates and maintain “atlas books” that serve to provide map reference of the City through “reporting districts”. Each reporting district is a half-mile by half-mile square that makes referencing easier for field personnel.

Original sanitary sewer and storm drain system maps are owned and maintained by the Engineering Division of the Public Works Department. The documents supporting compliance with the requirements for mapping are as follows:
• Tract Maps – available at the Engineering Division of the Public Works Department. • Sewer Atlas Maps – located within first responder’s vehicles, at the Public Works Utilities Yard, and at the Engineering Division of the Public Works Department. • Storm Drain Atlas Maps – located within first responder’s vehicles, at the Public Works Utilities Yard, and at the Engineering Division of the Public Works Department. • Sewer and Storm Drain GIS – Access available at City Hall and the Public Works Utilities Yard. • 2009 Sewer Master Plan– located at the Engineering Division of the Public Works Department.

City of Huntington Beach Sewer System Management Plan 25 The GIS Section also maintains the GIS information for the City’s storm drain system. Like the sewer atlas maps, the storm drain atlas maps are housed in the Engineering Division of the Public Works Department. Similar to the wastewater collection system maps, the storm drain system maps are regularly reviewed and updated as needed.

The GIS databases can be accessed via the City’s intranet. These databases are maintained via nightly server backup by the City’s Information Services Division. Local copies of the databases are backup up on a monthly basis by the GIS Section.

The hardcopy map books are available for reference either at City Hall, City Corporate Yard, City Utilities Yard, and the Emergency Operations Center. Copies of both the sewer atlas and storm drain atlas maps are kept in each Public Works maintenance field personnel/first responder’s vehicles and updated as needed.

A sample copy of the digitized mapping data is attached (Figure III-1).

City of Huntington Beach Sewer System Management Plan 27 Preventative Maintenance
The Order requires the City to describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at enhanced cleaning service areas. The Preventive Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders.

Funding for the operation and maintenance of the City’s sanitary sewer system is provided by the City’s sewer service fee. The sewer service fee was last adjusted the City Council in April 2019 and is dedicated to providing necessary funds for the sanitary sewer system.

The Wastewater section is composed of 19 full time employees. The organizational structure of the section is as follows:

Line Cleaning
Currently, the majority of the City’s sewer system is proactively cleaned with all gravity sewer pipe segments routinely cleaned and serviced every two (2) years.

The Wastewater Section owns and operates one (1) hydro-jetter truck, one (1) hydro-jetter trailer, three (3) combination high-velocity, hydro-cleaning trucks, and one (1) CCTV equipped truck. Routine preventative maintenance of the Wastewater equipment is performed by the Fleet Maintenance Personnel in the Operations and Maintenance Division of the Public Works Department.

Traffic control devices are established by the Equipment Operator and conform to the requirements of the latest California Manual on Uniform Traffic Control Devices (CA MUTCD) issued by the State of California, or the latest Work Area Traffic Control Handbook (WATCH) Manual.

Line cleaning work is primarily performed by City forces with contractors utilized on an as-needed basis.

Hydro-jetting is the primary method utilized to remove grease, roots, debris, and other obstructions from the sewer lines. When necessary, additional methods, such as the use of a chain-flail, are used to remove calcium buildup and other obstructions. The Leadworker is responsible for ensure the proper cleaning method used is appropriate for the type of sewer pipe being cleaned, i.e. vitrified clay pipe (VCP), polyvinyl chloride (PVC), etc. Sanitary sewer grit is disposed of in a grit chamber waste receptacle housed at the City Yard.

It should also be noted that the City historically treats root cutting as a normal part of line cleaning operations. A root cutter is carried on one (1) of the four (4) hydro-jet cleaning trucks, and is routinely used in the field. In addition, a contractor is scheduled to treat certain root locations in two-year treatment cycles, as needed.

At the beginning of each year, one of the Wastewater Leadworkers is assigned to manage the Line Cleaning Program and is responsible for scheduling line cleaning work for the rest of year. Under the general guidance of the Wastewater Crewleader, the Wastewater Leadworker develops a cleaning schedule that plans routine maintenance activities based on the results of the CCTV inspections, field observations, associated GIS data, and historical SSOs. Generally, work is planned by scheduling work via Reporting Districts (RD), and going from North to South and West to East. The Leadworker refers to progress made in the previous year as part of the planning process for scheduling of work in the current year. The three (3) cleaning crews generally follow the sewer system’s gravity flow, from the northeast part of the City to the southwest. Data gathered by CCTV inspections and entered into the GIS database is analyzed to establish the most effective cleaning schedule in each basin.

Once the schedule is developed, the Wastewater Leadworker develops a cleaning schedule that includes an estimated breakdown on a day-by-day basis. Work is scheduled such that cleaning begins at the far upstream end of the sewer segment and proceeds in a downstream direction until all work on the subject sewer segment has been complete. In the event the crew cannot access a manhole for cleaning procedures, the Equipment Operator shall immediately notify the Leadworker and document the occurrence on their Daily Worksheet.

Even with a regular cleaning schedule, some locations may still develop problems. These locations are placed on an “enhanced cleaning” location list and are cleaned more frequently. A list of the City’s enhanced cleaning locations is included in Appendix C. The frequency of the cleaning cycle varies based on the severity of the problem or the possible impact to the surrounding area. These cycles are City of Huntington Beach Sewer System Management Plan 29 reviewed by Wastewater personnel during the cleaning of the line and adjusted as necessary to ensure the prevention of future blockages. The City currently has 235 enhanced cleaning locations and assigns two (2) full-time employees to their maintenance.

Regarding documentation of schedule and conducted work activities, the City uses an in-house, computerized maintenance management system called HBSMS for recordkeeping and reporting purposes.

These records are kept and maintained by the Wastewater Supervisor.

Lift Station Maintenance
The City’s 27 sewer lift stations are generally reliable. To maintain their reliability the City performs preventative maintenance on daily, monthly, quarterly, and yearly schedules.

Lift stations are inspected weekly at a minimum. This includes visual inspection of all lift stations, exercising of valves and replacement of worn parts. Based on system design and capacity, some stations may require more frequent inspections. In addition to scheduled visits, emergency maintenance is performed on an as needed basis. Lift station maintenance and repair is performed by a combination of City forces and specialty contractors.

Wet wells are typically pumped down and cleaned at least four (4) times a year, or more often if necessary to prevent solids and grease build-up. Inspection of pumps (submersible and dry) and impellers are typically performed quarterly, but may be adjusted depending on pump motor hours. Inspection and exercising of all gate and check valves are also performed quarterly to ensure proper working order.

Cleaning and inspection of transducers and back-up floats are performed six (6) times a year to ensure proper performance. Inspection of lighting and alarm systems are performed weekly. Alarm system inspections and repairs are coordinated with the Utilities Technology Coordinator.

Hour meters on each motor is reviewed with lead pumps alternated at least weekly. A logbook of motor hour readings, dates, and maintenance performed is kept at each station. It is the responsibility of staff to enter any work performed at the station prior to leaving the station.

A quarterly inspection of all electrical motor control equipment is performed to identify poor connections and worn parts. This inspection includes infrared testing and panel maintenance. Inspection work is performed by the City Electrician or an appropriately licensed Contractor. Any deficiencies are reported to the Wastewater Supervisor for attention.

For emergency situations, the City owns 14 portable generators and five (5) onsite, emergency generators to provide power to the sewer lift stations in the event of an unforeseen power failure and/or planned SCE outages. A copy of the SCE Rotating Outages Map is included in Figure IV-1.

As part of routine weekly inspections, the onsite emergency back-up generator is visually inspected. At least quarterly, the generator is operated under load to ensure proper operation per operating permit requirements. This test conducted by tripping power to the station and observing a successful transfer to generator power for at least 15 minutes.

The City’s warehouse maintains adequate stock of essential parts and equipment along with additional pumps and motors for all 27 sewer lift stations. Each lift station is design to be redundant and can handle normal incoming flows with only one pump. The secondary pump is utilized if the primary pump fails to operate, or is down for repair. The Wastewater Section owns two (2) 6-inch bypass pumps and six (6) 3- inch bypass pumps available for emergency use.

City of Huntington Beach Sewer System Management Plan 30 Float switches are also set up to run the pumps in the event of a control panel failure. Lastly, an automated telemetry system monitors the stations 24-hours a day and reports any potential issues to standby personnel.

At the beginning of each year, one of the Wastewater Leadworkers is assigned to manage the Lift Station Program and is responsible for scheduling lift station cleaning to ensure continued and proper operation.

Under the general guidance of the Wastewater Crewleader, the Wastewater Leadworker develops a cleaning schedule and/or repair schedule that plans routine maintenance activities based proactive, preventative maintenance practices the help reduce costs and increase equipment reliability and lifespan.

Regarding documentation of schedule and conducted work activities, the City uses an in-house, computerized maintenance management system called HBSMS for recordkeeping and reporting purposes.

These records are kept and maintained by the Wastewater Supervisor.

As part of lift station inspections the following information is collected: date, time, initials of City personnel or contractor performing inspection, meter/hour readings for each pump-motor, general appearance, any maintenance and/or repairs performed, date of maintenance and/or replacement of pump and equipment, and other remarks as needed for future reference.

In addition, all work performed is recorded in a written “Daily Log” that is collected and compiled by the Leadwork at the end of the year. The Annual Daily Log Book for each year is kept for a minimum of five (5) years, or per the City’s Record Retention Policy, whichever is longer in duration.

Manhole Monitoring System
The City of Huntington Beach, Utilities Division installed 27 Smart Cover with sensor technology at strategic locations in the sewer system pipelines to generate an alert with any potential capacity constraints and manholes with potential for vandalism or illegal dumping. The sensors trigger alarms in the case of surcharging beyond preset levels or in the case of intrusion. The Smart Covers are placed in areas with historic high maintenance and at the area of first discharge proximate to a lift station.

Maintenance is performed in accordance with manufacturer’s recommendations and is contracted out directly to the Smart Cover vendor. Maintenance is performed on an annual basis and involved inspection of the unit and replacement of the battery. Defective units are replaced and/or repaired on an as-needed basis. Replacement/repair records are kept and maintained by the Wastewater Supervisor.

City of Huntington Beach Sewer System Management Plan 31 Figure IV-1 – SCE Rotating Outages Map

City of Huntington Beach Sewer System Management Plan 32 Closed Circuit Television Program
The Wastewater Supervisor oversees the CCTV Inspection Program. All CCTV inspection work is completed by certified National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP) trained operator(s) using established PACP coding and observations. The City intends to CCTV its entire system over the next five (5) years via Contractors, with the long-term goal of updating Citywide CCTV inspections every 5-10 years. Based upon these CCTV inspections and evaluations, routine maintenance is tailored to meet the actual needs of the system including updating the City’s capital improvement program (CIP) for system rehabilitation and replacement.

The City owns, operations, and maintains one (1) CCTV truck for localized CCTV inspections or sewer pipeline. The Leadworker overseeing the Line Cleaning Program also serves as the lead coordinator of the CCTV crew. For large-scale CCTV inspections, certified Contractors are used.

Prior to CCTV inspection, sewers are cleaned by removing grit, loose solids, grease, and any construction debris that are present. Cleanings are typically completed within 72 hours, and no less than one hour, prior to inspection. The City crew and/or Contractor traps all debris at the downstream manhole and properly disposes of debris within the pipeline.

All CCTV cameras have pan-and-tilt capabilities with a minimum of 460 lines of resolutions and meet Cal-OSHA requirements for operating in the sanitary sewer environment. Video inspection is conducted at a rate that does not exceed a traverse rate of 30 feet per minute. Video inspections for each pipe segment, e.g., manhole to manhole, are identified with an initial test screen and completed in accordance with PACP standards with inspection and reported submitted in a NASSCA-compatible format.

All observations and defects are documented in a database that included the digital video recordings and digital photographs. Each video clip and photograph provided corresponds to inspection data in the database and is properly linked to the appropriate video clip and photos. The severity of each defect or observation is recorded and rated using PACP codes as outlined in NASSCO’s PACP Reference Manual.

A minimum of two (2) photographs of each defect is taken, one (1) with a perspective view and one (1) with a close-up view. One (1) photograph is required for each lateral connection looking directly at the connection and from each manhole, from the bottom of the manhole looking up.

Digital photographs in JPEG format are made for all recorded defect observations. JPEG images are captured at a minimum resolution of 640x480 pixels per inch. At a minimum, all photographs shall be named consisting of the following descriptions: “from manhole station number”, “to manhole station number”, and eight digit inspection date.

After CCTV inspections are complete, as submittal review package consisting of a hard drive or DVD(s) and printed report is prepared. The hard drive or DVD(s) contain the inspection database, videos, and photo files. The printed report contains the footage calibration report for each camera used and PACP certificate copies for all CCTV equipment operators.

Once the final review is complete, a final report and submittal is prepared that includes all video recordings, image files, and databases on a maximum of 20 DVDs or one (1) external hard drive. If a hard drive is submitted, the submittal shall include the power cord and USB connection cable. DVDs or the external hard drive, binder cover, and binder spine label shall include the following computer- generated labels: Public Works Utilities Division – Wastewater Section, City Crew or Contractor Name, Project Name, Start Date of CCTV Inspections, and Finish Date of CCTV Inspections.

City of Huntington Beach Sewer System Management Plan 33 Sewer Lateral Program
The City of Huntington Beach has a Sewer Lateral Program which has been in place since January 2008.

Per Section 14.54.035 Maintenance and Repair of the Huntington Beach Municipal Code, the:

City will pay the cost of repair and maintenance of all lateral lines from the City- owned sewer main through the public right-of-way to the private property line. The owner is responsible for all costs of repair and maintenance of all lateral lines on private property not within the public right-of-way.

Historically, it was the property owner’s responsibility maintain and repair the entire sewer lateral up to the point of connection to the public sewer main. This differed from standard municipal practice where cities take full or partial responsibility for maintaining the public portion of the lateral, with the property owner responsible for the private side of the lateral. In January 2008, the Municipal Code was updated to match standard municipal practice and transferred responsibility for maintaining the public portion of the lateral from the main to the property line to the City of Huntington Beach.

The Sewer Lateral Program is a response driven program that facilitates the repair or replacement of sewer laterals on an as-needed basis. As part of the Sewer Lateral Program, homeowners experience problems with their sewer lateral can notify the Public Works Department, Utilities Division, to coordinate a repair. CCTV inspection of the sewer lateral is conducted by the property owner as part of the investigation process. Depending on the situation, there are typically two options for repair, e.g. slip lining or lateral replacement, which is completed by City forces.

As part of the repair, tree roots are cut and a sewer cleanout is added at the property line, typically just behind the sidewalk. The sewer cleanout designates the transition between the public and private portion of the sewer lateral and facilitates easier maintenance in the future. The City is responsible for the replacement, repair, and/or lining of the portion of the sewer within the public right-of-way. Any sewer replacement, repair, and/or lining on private property remains the responsibility of the owner.

The Sewer Lateral Program is scheduled on a daily basis by the Leadworker under the general oversight of the Wastewater Crewleader. A four (4) man crew with four (4) service trucks, one (1) backhoe, and one (1) trailer-jetter implement the Sewer Lateral Program four (4) days a week, 10 hours per day.

All maintenance and repair work conducted as part of the Sewer Lateral Program is documented via the City’s HBMS Work Order Management System. A copy of the Sewer Lateral Program and procedure is included in Appendix D.

Rehabilitation and Replacement Plan
Every Enrollee is responsible for developing a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and CCTV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. The rehabilitation and replacement plan should include a CIP that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan.

The City has an adopted Sewer Master Plan dated May 2003 that was recently updated by the firm of Kennedy-Jenks Consultants. The Sewer Master Plan evaluates the comprehensive condition of the City of Huntington Beach Sewer System Management Plan 34 Wastewater system including lines and equipment. Update of the City’s Sewer Master Plan is currently planned to start in 2022 with completion scheduled for Summer 2023.

Per the current Sewer Master Plan, the City’s primary collection system generally appears to have adequate hydraulic capacity. The short term rehabilitation and replacement plan is focused primarily on sewer lift station replacement and sewer lining. The City currently has 27 sewer lift stations and budgets to replace one (1) sewer lift station per year. The current FY 2021-22 budget for sewer lift station replacement is approximately $4 million per year. The scope of work for each sewer replacement project includes the full replacement of the sewer lift station, which includes but is not limited to: wet well, pumps, motors, electrical equipment, telemetry, and appurtenances. Onsite emergency power is included in projects when feasible. For sewer lining projects, the City dedicates approximately $1 million per year toward sewer lining. Pipeline sections scheduled for replacement are guided by CCTV inspections and per feedback received from the Wastewater Supervisor and Wastewater Operations Crewleader based on current field conditions.

Long-term CIP development is guided by the City’s Sewer Master Plan. Identification of structural deficiencies in the sewer lines is performed via television inspection of the City’s sewer lines. Damaged or broken sewer lines, which could result in a sewage spill, are designated as high priority. The lines in need of repair are evaluated and scheduled to either be slip-lined or replaced.

The City of Huntington Beach adopted a Sewer Service Charge in 2001 and created a Sewer Service Fund. The Sewer Service Fund revenue is designated solely for the rehabilitation, replacement, repair, and maintenance of City-owned sewers, sewer lift stations, and sewer related facilities. This is in accordance with the California Health and Safety Code Section 5470, and is included in Ordinance Title 14 – Water and Sewers, which adds Chapter 14.54 to the Huntington Beach Municipal Code.

Public Works is the City of Huntington Beach’s department responsible for the sewage collection system. The maintenance program consists of a recordkeeping and reporting system, a program to address requests for service from the public, an established cycle for regular cleaning as well as an “Enhanced cleaning list”, a 24- hour emergency response program, an inspection program, a GIS mapping program, and a sewer lift station maintenance program.

Table VI-1 denotes the budget for the Wastewater section operations and capital improvements. The FY 2021-22 budget includes $4,000,000 for sewer lift station reconstruction of the Humboldt Lift Station.

City of Huntington Beach Sewer System Management Plan 38 SECTION 5 – DESIGN AND PERFORMANCE PROVISIONS
This chapter references the design and construction standards and specifications for new sewer systems, pump stations, and other appurtenances, and for the rehabilitation and repair of existing sewer systems.

Also included are the procedures and standards for the inspections and testing of these facilities.

The Order requires the following design and performance provisions:
a. Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations, and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and

b. Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.

Design of the City’s sanitary sewer system is performed by licensed California registered civil engineers under the general oversight of the City Engineer. Construction management, inspection, and testing is performed by qualified City personnel or consultant firms, also under the general oversight of the City Engineer. Contractors must be appropriately licensed and insured.

Design and Construction Standards and Specifications, and Standards for the Inspection and Testing of New Sewer Facilities
“GREENBOOK” Standard Specifications for Public Works Construction, latest edition The City utilizes the latest edition of the “Standard Specifications for Public Works Construction” or “Greenbook” specifications for general construction and inspection of sewer facilities. The “Greenbook” is a readily available document, which is utilized by the majority of public agencies in Southern California and throughout the United States. Due to its large size and regular update every three (3) years, it is not included in this Plan.

City of Huntington Beach Standard Plans, Section 500
The City’s Standard Plans and Specifications provides specific design criteria for construction and inspection for the sanitary sewage system. The City Standard Drawings (Section 500) can be accessed on the City’s website at the following link:
https://www.huntingtonbeachca.gov/government/departments/public_works/standard_plans.cfm City of Huntington Beach Sewer Master Plan
The City utilizes the City of Huntington Beach Sewer Master Plan, Final Report, May 2003, by Kennedy Jenks Consultants, to prioritize Sewer Lift Station replacement and gravity sewer segments that are considered to be hydraulically deficient.

City of Huntington Beach Sewer Lift Station Design Manual The City utilizes the City of Huntington Beach Sewer Lift Station Design Manual, by Camp Dresser & McKee Inc., August 2001, to provide a consistent and uniform design criteria for the replacement of City owned Sewer Lift Stations.

At Sewer Lift Stations, wherever possible, the City has installed natural gas powered site generators to provide a redundant energy supply in case of electrical power outage. The City also has mobile trailer City of Huntington Beach Sewer System Management Plan 39 mounted generators available to power the Sewer Lift Stations that lack onsite backup generators. The City also has the capability to pump sewage with mobile diesel powered pumps, which couple to the existing force mains at each Sewer Lift Station.

City of Huntington Beach, Design Standards for Instrumentation, Controls, and Electrical The City recently developed design standards for instrumentation, controls, and electrical equipment installations for SCADA equipment for Utilities Division facilities. The purpose of the document is to standardize controls system design and implementation across Utilities Division infrastructure.

Standard Plans and Specifications for Private Sewer Lift Stations The City has drafted a set of requirements for privately owned sewer lift stations. These standards are not yet incorporated into a City of Huntington Beach Standard Plan, or Standard Specification. However, the City anticipates the adoption of these Standard Plans and Specifications in the near future. These standards will allow the City’s sewer maintenance personnel to respond to emergency disruptions of service at private facilities, with standard City equipment, such as portable pumps and generators.

City of Huntington Beach Sewer System Management Plan 40 SECTION 6 – OVERFLOW EMERGENCY RESPONSE PLAN
Under the Order, each Enrollee shall develop and implement an Overflow Emergency Response Plan that identifies measures to protect public health and the environment.

At a minimum, this plan must include the following:
a. Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
b. A program to ensure an appropriate response to all overflows; c. Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the Waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs of NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification; d. Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;
e. Procedure to address emergency operations, such as traffic and crowd control and other necessary response activities; and
f. A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to Waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.

In 2002, the City developed an SSO Emergency Response Plan, to meet the aforementioned criteria. All public spills, and any known private spills that reach storm drain facilities, are reported to the State Water Resources Control Board via the California Integrated Water Quality System Project (CIWQS) online reporting program.

All discharges of sewage, whether a sanitary sewer overflow or a subsurface sewer leak, shall be first be reported to the Public Works Department, Utilities Division. Leadworkers or a higher position will make the initial data submission to CIWQS. The Wastewater Section Supervisor or his/her designee, will be responsible for reporting all discharges of sewage immediately to applicable Federal, State, regional and local agencies. The California Emergency Management Agency and the Regional Water Quality Control Board are contacted by telephone. If the spill enters a county channel, the County of Orange Environmental Resources Department is notified by telephone. The Orange County Health Care Agency and the Regional Water Quality Control Board are also provided a copy of the spill report, normally via facsimile copy. After the draft SSO report is input into CIWQS by the Wastewater Section Supervisor, the Deputy Director of Public Works-Utilities certifies the final report and submits it to the SWRCB.

Any discharge caused by defects in the system that cannot be corrected by the Utilities Division through normal maintenance efforts will be referred to the Engineering Division for assessment and recommended action.

City of Huntington Beach Sewer System Management Plan 41 Discharges that are determined to be caused by activities on private property will be directed to the Public Works Department, Wastewater Section for cleanup, billing and agency notifications.

Compliance Documents
The SSO Emergency Response Plan is documented as Administrative Regulation AR808, a copy of which is included in Appendix I.

City of Huntington Beach Sewer System Management Plan 42 SECTION 7 – FATS, OILS, AND GREASE CONTROL PROGRAM
Under the Order, each Enrollee is required to evaluate its service area to determine whether a FOG Program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
a. An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
b. A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; c. The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
d. Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices maintenance requirements, BMP requirements, record keeping and reporting requirements.
e. Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; f. An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and g. Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.

FOG Program Development and Implementation
The City of Huntington Beach FOG Control Program was initially developed and implemented in 2004 as a preventative measure to reduce the potential for SSOs. The development of the FOG Control Program included the following elements that were the foundation of the program development and implementation phase:
• Assessment of the sources of sanitary sewer overflows; • Inventorying grease producing food service establishments (FSEs); • Adoption of a FOG ordinance (Control and Regulations of Fats, Oils, & Grease ordinance); • Adoption of a fee resolution to fund the program;
• Identifying resources and staff to develop and implement the FOG Control Program; • Implementation of a FOG Control Inspection program; and • Outreach to the public.

City of Huntington Beach Sewer System Management Plan 43 The program was developed in collaboration with the OC SAN and member agencies as a shared-cost cooperative effort to develop and implement FOG Control Programs that met the requirements of the 2004 SSO WDR and that were consistent between the member agencies. The cooperative collaboration included the development of the FOG Control Program Best Management Practices (BMPs) Training Manual for Food Service Establishments (Appendix J) and the FOG Impact Study (Appendix K).

The program has undergone some minor changes since its inception in 2004 with adoption of the amended FOG ordinance (Municipal Code Section 14.56) as the most notable programmatic change.

Assessment of Sources of Sanitary Sewer Overflows (SSOs) In 2004, City staff conducted an informal review of SSOs from the City’s sanitary sewer system in the previous three years (2001-2003) to determine the cause of the SSOs. Although at the time of the informal review there were no formal records kept regarding the source of the SSOs, it was estimated that FOG related blockages resulted in more than half of the SSOs. This estimate was based on anecdotal evidence and historical knowledge of “enhanced cleaning areas” that were known to accumulate grease.

Inventory of Grease Producing Food Service Establishments The City continually updates its inventory of grease producing FSEs on a monthly basis. This process is initiated at the beginning of every month by staff reviewing all business licenses issued to FSEs the previous month and assessing the need to include the FSE(s) in the FOG Control Inspection program.

The basis for inclusion in the program is whether the FSE processes and/or prepares beef, poultry, or fish.

This may require a site visit by City staff to confirm if the menu is not available online. The inventory of FSEs in the FOG Control Inspection program ranges between 270 to 300 FSEs.

The inventory is divided into two categories; FSEs with a grease control device (GCD), which includes mechanical grease interceptors and/o gravity grease interceptors, and FSEs without a GCD. The current inventory of FSEs in the FOG Control Program has 286 FSEs of which 70% (201 FSEs) have a GCD and 30% (85 FSEs) do not have a GCD.

Adoption of FOG Ordinance
The City adopted the Control and Regulation of Fats, Oils, and Grease Ordinance in 2004 (Municipal Code Section 14.56) to grant the legal authority to:
i. Declare sewer system overflows as a public nuisance; ii. Require FOG pre-treatment for FOG producing FSEs;
iii. Grant City staff authority to conduct inspections under the FOG Control Inspection program; iv. Establish a minimum frequency for maintenance of FOG pre-treatment devices; v. Require the implementation of FOG best management practices (BMPs); vi. Establish enforcement penalties and cost recovery procedures for violations of the FOG ordinance and/or SSOs.

In 2013, the City amended the Control and Regulation of Fats, Oils, and Grease ordinance to include the following provisions:
i. FOG pre-treatment required of existing FSEs that under-go a change in ownership; City of Huntington Beach Sewer System Management Plan 44 ii. FOG pre-treatment required of FSEs that apply for building permits in excess of $50,000 in improvements or involving one or a combination of the following:
a. Under slab plumbing in the food processing/preparation area; b. 30% increase in the net public seating area;
c. 30% increase in the kitchen area;
d. Any change in the size or type of food preparation equipment. iii. Authorizes the Director of Public Works to require FSEs that have two or more SSOs with a one year period or three within a five year period to install FOG pre-treatment; iv. Require routine cleaning of private sewer laterals at a minimum frequency that prevents SSOs from occurring and that no more than 25% of the sewer lateral capacity is to be impacted by the accumulation of FOG or other substances.

Adoption of Fee Resolution
In 2004, the City adopted a Fee Resolution (Resolution No. 2004-89) to establish a fee structure to charge FOG producing FSEs enrolled in the FOG Inspection program a monthly fee (FOG Control Fee) to fund the FOG Control program. The FOG Control Fee is a two-tiered monthly fee that is assessed in a similar fashion to the utility user fee. The first tier is for FSEs that have FOG pre-treatment. These FSEs are charged a lower rate of approximately $0.40/day. The second tier is for FSEs that do not have a FOG pre- treatment device. These FSEs are charged approximately $1.05/day. The higher rate for FSEs without FOG pre-treatment was established to fund the additional inspection costs of these facilities as they are inspected bi-annually year versus FSEs that have FOG pre-treatment that are inspected annually.

Identifying Resources & Staff to Develop and Implement the FOG Control Program Following the initial assessment 2004 of the FSEs that would be enrolled in the FOG Control Program, the City identified the staffing and resources required to develop and administer a FOG Control Program.

The initial assessment in 2004 identified approximately 300 FSEs as potential enrollees in the FOG Control Program. This initial assessment was used as a baseline to assess the staffing and other required resources. Based on this initial assessment, the City identified the need to hire at least one full time employee and augment the hiring of the new employee with assistance from Wastewater staff from the Department of Public Works’ Utilities Division.

In 2005, the City hired an Environmental Specialist to develop and administer the FOG Control Program.

Over the years, the program has dovetailed with the Storm Water/Urban Runoff program and now has two Environmental Specialists that report to the Environmental Services Manager administering the FOG Control Program.

The Environmental Specialists coordinate with the Wastewater Section staff to respond to SSOs, identify potential “enhanced cleaning areas” in the sanitary sewer system, conduct CCTV inspections of sewer mains and laterals, and conduct training and outreach to the public.

Implementation of FOG Control Inspection Program
The FOG Control Program consists of the following elements:
• Identification of potential FOG Control Inspection Program enrollees; City of Huntington Beach Sewer System Management Plan 45 • Inspection of FSEs in the FOG Control Inspection Program; • CCTV inspection of sewer laterals.

Identification of FSEs to Enroll in FOG Control Inspection Program On a monthly basis, Environmental Specialists administering the FOG Control Program review the City’s business license database to identify new FSEs that would potentially need to be enrolled into the FOG Control Inspection Program. Staff confirms the status by reviewing the menu (if available) or conducting a site visit once the FSE has opened for business. Once confirmed, the new FSEs are enrolled and inspected at least once a calendar year.

Inspection of FSEs in the FOG Control Inspection Program The FOG Control Inspection Program consists of two tiers; high priority and low priority. The FSEs that have a GCD are considered a lower threat to introducing FOG to the City’s sanitary sewer system and are thus designated a low priority facility and inspected only once a calendar year. The FSEs without any FOG pre-treatment are categorized as high priority since there is a greater potential for these FSEs to introduce FOG into the City’s sanitary sewer system. These facilities are inspected at least twice a calendar year.

Minimum FOG Best Management Practices (BMPs)
All FSEs in the FOG Control Program are required to implement the minimum FOG BMPs. These include proper disposal of waste oil/grease, dry wiping cookware/serving utensils to remove food and grease, wiping down of hood filters prior to washing, using absorbent to clean grease spills, and training staff every six months and all new hires within two weeks of hire.

In addition to the minimum BMPs, FSEs with FOG pre-treatment are required to service the GCD on a quarterly basis at minimum. This is the minimum requirement and FSEs that consistently have FOG percentages above 25% of the total hydraulic volume of the GCD are required to increase the service frequency to every two months or even monthly in order to prevent exceeding the 25% FOG threshold.

Other additional BMPs include requiring FSEs to service internal (kitchen) and external sewer laterals on a routine basis to remove FOG build-up in the lines.

The most important element of all of the BMPs is the employee training. City staff provides FSEs a copy of the FOG Training Manual at the time of the initial inspection. The FOG Training Manual (Appendix J) is a three ring binder that includes all of the minimum BMPs required and an Employee Training Log to document all training. The FOG Training Manual also includes a DVD with all of the training materials and BMPs in four languages; English, Spanish, Mandarin, and Vietnamese.

Outreach to the Public
The City has developed a FOG Program webpage on its website https://www.huntingtonbeachca.gov/government/departments/public_works/fog/ . The webpage targets
both the general public and FSEs enrolled in the FOG Control Inspection Program. The webpage contains information for the general public on methods of how to properly dispose of FOG, and how to prevent FOG blockages.

For FSEs in the FOG Control Inspection Program, the webpage includes links to the FOG Training Manual that FSEs can download and/or print and links to the FOG training videos in English and Spanish.

City of Huntington Beach Sewer System Management Plan 46 Record Keeping and Reporting
FSE’s are responsible for maintaining training logs, GCD service records, and grease collection/disposal records for a minimum of four (4) years. All records are kept onsite by FSE’s and made available during their routine inspections. Although not a mandatory requirement, the City provides regular reports on the FOG program to the SWRCB as part of its Annual NPDES Report submittal.

Compliance Documents
The FOG Training Manual for Food Service Establishments is included in Appendix J and FOG Impact Study is included in Appendix K.

City of Huntington Beach Sewer System Management Plan 47 SECTION 8 – SYSTEM EVALUATION AND CAPACITY

ASSURANCE PLAN
The Order requires that each Enrollee shall prepare and implement a capital improvement program (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
a. Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;
b. Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and c. Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternative analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. d. Schedule: The enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a) – (c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14.

Evaluation
The City utilizes the City of Huntington Beach Sewer Master Plan, Final Report, May 2003, by Kennedy Jenks Consultants, to prioritize sewer lift station replacement and the replacement of those gravity sewer segments that are considered hydraulically deficient. The evaluation included a limited field flow monitoring program to obtain actual field measure wastewater data and a desktop I&I analysis to assess potential I&I areas of the City. The recommended capital improvements within the report were developed to correct system deficiencies, provide the ability to serve future growth, and to replace aging infrastructure to improve system reliability.

The City’s 27 sewer lift stations were also analyzed as part of the Sewer Master Plan. Based on this analysis, and with input from the City’s maintenance staff, a priority list was established for rehabilitation and/or replacement of these lift stations.

Although the City is approximately 97% built out with only a minimal increase in future wastewater flows projected, the Sewer Master Plan identified possible deficiencies for further site specific evaluation in approximately nine miles (or less than 3%) of the entire gravity system. In 2008, the City completed an evaluation of those segments that exceeded the design criteria for “new” sewers. It was found that in all but two cases, the actual flow in the pipes was less than identified in the Sewer Master Plan’s desktop analysis. One segment, located on Beach Blvd., was upsized in 2016. The other segment was located City of Huntington Beach Sewer System Management Plan 48 immediately downstream of the Edinger Lift Station. Modifications to that sewer lift station were made to limit the amount of flow discharged to this segment.

With these two improvements, the City’s gravity sewer system does not exhibit any capacity issues, based on existing uses. In the event properties are redeveloped to a higher density that might impact the downstream sewer system, those property owners are required to provide an engineering analysis and make the necessary downstream improvements as a condition of approval of those projects.

Design Criteria
The City utilizes industry standards as the design criteria for its sanitary sewer system. All design work is conducted by registered California professional engineers and all contractors are required to be appropriately license and insured. The City required that all sewer infrastructure design be compliant with the “Standard Specifications for Public Works Construction” or “Greenbook”, current edition, the City of Huntington Beach Standard Plans, the City of Huntington Beach Sewer Lift Station Design Manual, and City of Huntington Beach Design Standards for Instrumentation, Controls, and Electrical, along with all other relevant building code standards and regulations.

Wastewater flow criteria such as, but not limited to, land use wastewater generation factors, peaking factor, I&I, design capacity, pumping capacity, wet well sizing, and other design criteria is detailed and including within the City’s Sewer Master Plan, included as Appendix F.

Capacity Enhancement Measures
The City has incorporated several capacity enhancement measures into its sanitary sewer system. The City has an I&I program that rehabilitated existing sewer pipe via in situ lining technology to prevent storm water and groundwater from entering the system. The City’s CCTV Inspection Program and proactive Line Cleaning Program ensure the sanitary sewer system can handle its wastewater flows as design. The CCTV Inspection Program provides the City with visual data on internal deficiencies while the Line Cleaning Program keeps the sanitary sewer lines free of accumulations of FOG, roots, and other debris.

The City also updated its CIP to regularly fund a sewer lining projects as part of the I&I program.

Approximately, $1 million is dedicated annually toward this program. Furthermore, the City budgets for the replacement of one (1) sewer lift station per year to ensure that every sewer lift station is appropriately sized and in good working condition to handle its design flow.

As a result of the City’s sewer master planning efforts, Chapter 14.36 of the City’s Municipal Code was updated to increase the sewer connection fee commensurate with the necessary capital improvements.

The projects identified within the 2003 Sewer Master Plan report as being hydraulically deficient have already been replaced or remediated. The City considers the 2003 Sewer Master Plan viable, since trends in the generation of sewage in Huntington Beach have shown a decrease in sewage per capita and an overall decrease for the City as a whole even though the City’s population has increased since 2003. Data from the OC San supports this conclusion. The decline in sewage flows can be attributed to a trend towards water conservation and a decline in infiltration and inflow resulting from the City providing aggressive sewer lining projects.

To further substantiate the adequacy of the 2003 Sewer Master Plan, the City will undergo a flow analysis study in key segments of the collection system and compare the actual flows to the flows and capacities provided in the 2003 document. The study is currently planned to be implemented as part of the City’s 2022 Sewer Master Plan Update.

City of Huntington Beach Sewer System Management Plan 49 Schedule
The City’s current CIP lists improvements to the sanitary sewer system for the next five (5) years. The CIP is periodically reviewed with changes being made to the project list and start dates to meet the changing needs of the City. The CIP also contains budgetary cost projections for the listed projects.

Funding is provided for the replacement and rehabilitation of the City’s sanitary sewer by the Sewer Enterprise Fund balance.

Since adoption of the Sewer Master Plan, sewer lift stations B and #15 have been eliminated and twelve lift stations have been rebuilt. The City has sufficient sewer funding and plans to continue with replacing aged sewer lift stations at an average rate of one (1) sewer lift station per year, as needed. In addition to the replacement of aged sewer list stations, the City has also installed magnetic flow meters, and the SCADA capability adequate to capture flow data from these newer lift stations.

Regarding sewer pipelines, the City regular allocates funds for sewer lining every year. Replacement and/or upsizing of sewer pipe is performed on an as-needed basis. The City is currently plans to update its Sewer Master Plan starting in 2022. Future CIP budgets will be adjusted in consideration of CIP project recommendations provided as part of the Sewer Master Plan Update.

8.1 Compliance Documents
The City’s 2003 Sewer Master Plan, prepared by Kennedy-Jenks Consultants in 2003 can be found in Appendix F. The Sewer Capacity Analysis, prepared by AKM Consulting Engineers in 2009 can be found in Appendix G.

City of Huntington Beach Sewer System Management Plan 50 SECTION 9 – MONITORING, MEASUREMENT, AND PROGRAM

MODIFICATIONS
Under the Order, Enrollees shall monitor and measure the effectiveness of the SSMP and shall make modifications as necessary to maintain the program’s effectiveness. This section describes City of Huntington Beach’s monitoring, measurement and program modification program.

Under the Order, the Enrollee shall:
a. Maintain relevant information to establish and prioritize appropriate SSMP activities; b. Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP;
c. Assess the success of preventive maintenance activities; d. Update program elements, as appropriate, based on monitoring of performance evaluations; and
e. Identify and illustrate SSO trends, including frequency, location and volume.

Performance Measure Identification
Improved wastewater infrastructure performance is a core task of any properly managed utility. The City of Huntington Beach is committed to continuous improvement by:
• Utilizing a formalized program for continuous improvement • Institutionalizing continual evaluation of its performance • Identifying opportunities for continuous improvement
To accomplish the above goals, the City of Huntington Beach has established a number of performance measures and routinely monitors progress in meeting those performance measures. The performance measures relating to each SSMP program element are listed in the following subsections.

Goals
The overall goal of the SSMP is to achieve zero preventable SSOs. While the City of Huntington Beach recognizes that US EPA and State of California regulatory agencies are encouraging a zero SSO goal, the random and unexpected nature of many SSO events make it challenging to achieve a goal of zero. SSOs that are caused by such acts as vandalism, contractor or property owner “hits,” excessive customer discharge of FOG or extreme weather events that are potentially able to be minimized by the utility, cannot always be prevented or totally eliminated.

Consequently, the City of Huntington Beach has established a performance measure of zero preventable SSOs. SSO events will continue to be tracked by the City of Huntington Beach for cause and for location to identify “enhanced cleaning service areas” for additional preventive maintenance activities, but overall success of the program will be measured by progress in reducing the number of preventable SSO events towards an ultimate goal of zero preventable SSOs.

City of Huntington Beach Sewer System Management Plan 51 Organization
The City of Huntington Beach has established an effective organizational structure for sewer management, operations and maintenance. The success of this structure depends, however, in retaining existing staff and in filling those staff positions that do become vacant with skilled and talented individuals. To measure organizational success, the City of Huntington Beach will monitor:
• Staff resignations as a percent of filled positions
• Staff vacancy rate as a percent of budgeted positions • Staff training and certification expiration and renewals Establishment of a performance goal associated with the performance measure for staff resignations may need to take unavoidable resignations, such as those due to retirements or disability, into account.

Legal Authority
The City of Huntington Beach has well-defined legal authority in place for the SSMP programs. No additional goals or performance measures are needed in this area at this time.

Operation and Maintenance Program
The City of Huntington Beach has established a number of performance measures for collection system O&M. The following lists the key performance measures for the SSMP program:
• Miles of sewer cleaned
• Miles of laterals cleaned
• Miles of sewers inspected
• Miles of sewer repaired/replaced
• Number of laterals repaired
• Number of sewer cleanouts installed
• Number of sewer investigations
• Number of manholes treated (roach control)
• Number of stoppages cleared
• Number of SSOs
• Number of wet wells cleaned
• Number of pump station inspections
• Miles of force mains walked for visual inspection
• Number of force main air relief valves inspected

City of Huntington Beach Sewer System Management Plan 52 These performance measures are reported in the Annual Sewer Service Fund Performance Audit as codified by Huntington Beach Municipal Code 14.54.070.

Overflow Emergency Response Program (OERP)
The following performance measures will be tracked to monitor OERP performance:
• Time elapsed from SSO notification call received to time responders arrive on-site • Time elapsed until overflow is controlled
Fats, Oils and Grease (FOG) Control Program
The following performance measures will be tracked to monitor FOG control effectiveness:
• Number of grease-related SSO events
• Number of Food Service Establishment (FSE) inspections performed • Number of FSE enforcement actions initiated
• Number of FSE enforcement actions resolve
Design and Performance Provisions
The following performance measures will be tracked to monitor the effectiveness of the City of Huntington Beach’s design and construction standards and specifications:
• Number of warranty inspections completed
• Percent of warranty inspections requiring follow-up work by the contractor System Evaluation and Capacity Assurance Plan (SECAP)
The following performance measures will be tracked to monitor SECAP performance:
• Number of capacity-related SSO events (including wet weather-related SSOs) • Number of recommended Capacity Enhancement CIP Projects completed Monitoring, Program Modifications and Program Audits
The following performance measures will be tracked to monitor the effectiveness of the Monitoring program:
• On-time completion of bi-annual SSMP program review and self-audit Communication Program
The following performance measures will be tracked to monitor the effectiveness of the Communications program:
• Number of public information brochures, newsletters, or similar materials distributed • Number of public education events attended
City of Huntington Beach Sewer System Management Plan 53 • Number of public education presentations completed
Program Modification Plan
The success of the SSMP program elements should lead to a reduction of SSOs within the City of Huntington Beach collection system. If no reduction in SSOs is seen, the program elements will be critically reviewed to determine areas for improvement. Those program elements will be modified as needed to improve performance.

City of Huntington Beach Sewer System Management Plan 54 SECTION 10 – SSMP PROGRAM AUDITS
As a part of the SSMP, the permittee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluation the effectiveness of the SSMP and the Enrollees compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them.

Compliance Summary
The City uses the SSMP update process to identify actions for improving how it manages, operates, and maintains the collection system. This process identifies the tasks and actions that are required to meet SSMP goals and defines and prioritizes them. Resourcing and planning for delivery of the actions identified in the SSMP audit are incorporated into the City’s strategic planning process, described in Section 9 - Monitoring, Measurement and Program Modifications.

Schedule of Program Audits and Updates
The City monitors the performance of the collection system on an on-going basis through performance reviews. It also performs a formal audit of its SSMP every two years in accordance with the WDRs. The two-year frequency is the maximum allowed by the regulation; however this frequency is appropriate to the size of the City’s collection system and the historical number of overflows, and should be sufficient to identify any necessary improvements to the SSMP. The City will assess the need to audit the SSMP more frequently based on the performance of the sanitary sewer system using information from the key performance indicators and input from the Wastewater Department staff. Every five years, the City formally updates and recertifies the SSMP. Table 10-1 shows the timeline for SSMP audits and updates for the last five years and the anticipated schedule for the next five years.

2025 Biennial self-audit to commence in late 2024. Commence review and update of SSMP. 2026 5 year SSMP update.

Program Audit and Update Process
A team composed of City staff and management directly involved in the development and administration of the elements of the SSMP will be formed once every two (2) years to perform biennial self-audits in accordance with regulatory requirements for SSMP Program Audits. The team will be led by the Deputy City of Huntington Beach Sewer System Management Plan 55 Director of Public Works-Utilities and will meet in a series of in-person meetings over the course of approximately three months to evaluate the effectiveness of each SSMP element, identify any deficiencies, and make recommendations for improvements and updates. This will be conducted by answering a set of questions developed specifically for the purpose of the audit for each element of the SSMP. It also includes referencing and reviewing performance reports and capacity reports, flows, and other important metrics gathered in the past two years. These findings will be documented in an audit report. Upon completion of the audit, a quality control review of the audit report will be performed, with a focus on consistency, completeness, and inclusion of references and attachments as appropriate. The final audit report will be reviewed by the City’s LRO (Deputy Director of Public Works-Utilities) before final acceptance. Audit reports and related materials will be maintained in a hard copy and an electronic copy.

City of Huntington Beach Sewer System Management Plan 56 SECTION 11 – COMMUNICATIONS
The Enrollee shall communicate on a regular basis with the public on the development, implementation and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented.

The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee’s sanitary sewer system.

Compliance Summary
The City maintains a website (https://www.huntingtonbeach.gov/SSMP) to inform the public about the Sewer System Management Program. The website provides a full version of the SSMP, including all attachments, for public review. The City’s website is an effective communication source for providing information and news to the public. The website also provides information on reporting sewer system issues; includes phone numbers for reporting purposes during and after business hours.

The City uses an electronic application called MyHB for use with both iPhones and Android systems.

This application is a work-order system that allows the public to report issues of concern anywhere in the City (sewer non-emergency, storm drain non-emergency, odor issues, etc.). The City’s SSMP website includes a direct link to report sewer non-emergency issues.

During FOG inspections, City staff provides information to business operators on protecting the sewer system, avoiding sewer overflows, and how to report sewer related issues.

The City’s plan of communication with systems that are tributary consists of maintaining constant communication with neighboring agencies. Throughout the year, the City has several opportunities to regularly meet and communicate with local agencies through the CA WDR Group Meetings. The Wastewater Supervisor attends these meetings. The focus of the CA WDR Group is share information on everything related to sanitary sewer systems, including SSO notification, monitoring, reporting and requirements.

STATE WATER RESOURCES CONTROL BOARD
ORDER NO. 2006-0003-DWQ

STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS
FOR

SANITARY SEWER SYSTEMS
The State Water Resources Control Board, hereinafter referred to as “State Water Board”, finds that:

1. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as “Enrollees”.

2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.

3. Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO. A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.

4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractor- caused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system.

State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06

SEWER SYSTEM MANAGEMENT PLANS

5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions.

6. Many local public agencies in California have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order.

Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs.

7. SSMP certification by technically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately.

8. It is the State Water Board’s intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State.

9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary to assure compliance with these waste discharge requirements (WDRs).

10. Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion.

11. Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board’s intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board’s WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting.

REGULATORY CONSIDERATIONS

12. California Water Code section 13263 provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that:
x The discharges are produced by the same or similar operations; x The discharges involve the same or similar types of waste; x The discharges require the same or similar treatment standards; and x The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements.

This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state.

13. The issuance of general WDRs to the Enrollees will:
a) Reduce the administrative burden of issuing individual WDRs to each Enrollee;
b) Provide for a unified statewide approach for the reporting and database tracking of SSOs;
c) Establish consistent and uniform requirements for SSMP development and implementation;
d) Provide statewide consistency in reporting; and
e) Facilitate consistent enforcement for violations.

14. The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and non- contact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply.

Surface and ground waters throughout the state support these uses to varying degrees.

15. The implementation of requirements set forth in this Order will ensure the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each region and take into account the environmental characteristics of hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water.

16. The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements.

Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs.

17. California Water Code section 13263 requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance.

18. California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.

19. This Order is consistent with State Water Board Resolution No. 68-16 (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies.

20. The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code §21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in Section 15301, and §15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.

21. The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements.

22. The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs.

23. The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs.

IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following:

A. DEFINITIONS

1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include:
(i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and
(iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.

2. Sanitary sewer system – Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility.

Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs.

State Water Resources Control Board Order No. 2006-0003-DWQ Page 6 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 For purposes of this Order, sanitary sewer systems include only those systems owned by public agencies that are comprised of more than one mile of pipes or sewer lines.

3. Enrollee - A federal or state agency, municipality, county, district, and other public entity that owns or operates a sanitary sewer system, as defined in the general WDRs, and that has submitted a complete and approved application for coverage under this Order.

4. SSO Reporting System – Online spill reporting system that is hosted, controlled, and maintained by the State Water Board. The web address for this site is http://ciwqs.waterboards.ca.gov. This online database is maintained on a secure site and is controlled by unique usernames and passwords.

5. Untreated or partially treated wastewater – Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks.

6. Satellite collection system – The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary.

7. Nuisance - California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.

B. APPLICATION REQUIREMENTS

1. Deadlines for Application – All public agencies that currently own or operate sanitary sewer systems within the State of California must apply for coverage under the general WDRs within six (6) months of the date of adoption of the general WDRs. Additionally, public agencies that acquire or assume responsibility for operating sanitary sewer systems after the date of adoption of this Order must apply for coverage under the general WDRs at least three (3) months prior to operation of those facilities.

2. Applications under the general WDRs – In order to apply for coverage pursuant to the general WDRs, a legally authorized representative for each agency must submit a complete application package. Within sixty (60) days of adoption of the general WDRs, State Water Board staff will send specific instructions on how to State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 apply for coverage under the general WDRs to all known public agencies that own sanitary sewer systems. Agencies that do not receive notice may obtain applications and instructions online on the Water Board’s website.

3. Coverage under the general WDRs – Permit coverage will be in effect once a complete application package has been submitted and approved by the State Water Board’s Division of Water Quality.

C. PROHIBITIONS

1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited.

2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited.

D. PROVISIONS

1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action.

2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be:
(i) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree;
(ii) Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code;
(iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or
(iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board.

3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO.

4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains.

5. All SSOs must be reported in accordance with Section G of the general WDRs.

6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee’s efforts to contain, control, and mitigate SSOs when considering the California Water Code Section 13327 factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether:
(i) The Enrollee has complied with the requirements of this Order, including requirements for reporting and developing and implementing a SSMP; (ii) The Enrollee can identify the cause or likely cause of the discharge event; (iii) There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems.
(iv) The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee;
(v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for:
x Proper management, operation and maintenance;
x Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.);
x Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control);
x Installation of adequate backup equipment; and
x Inflow and infiltration prevention and control to the extent practicable.
(vi) The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs.

State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible.

The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following:
(i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure;
(ii) Vacuum truck recovery of sanitary sewer overflows and wash down water;
(iii) Cleanup of debris at the overflow site;
(iv) System modifications to prevent another SSO at the same location; (v) Adequate sampling to determine the nature and impact of the release; and
(vi) Adequate public notification to protect the public from exposure to the SSO.

8. The Enrollee shall properly, manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities.

State Water Resources Control Board Order No. 2006-0003-DWQ Page 10 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06

12. In accordance with the California Business and Professions Code sections 6735, 7835, and 7835.1, all engineering and geologic evaluations and judgments shall be performed by or under the direction of registered professionals competent and proficient in the fields pertinent to the required activities. Specific elements of the SSMP that require professional evaluation and judgments shall be prepared by or under the direction of appropriately qualified professionals, and shall bear the professional(s)’ signature and stamp.

Sewer System Management Plan (SSMP)
(i) Goal: The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system.

This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur.
(ii) Organization: The SSMP must identify:
(a) The name of the responsible or authorized representative as described in Section J of this Order.
(b) The names and telephone numbers for management,
administrative, and maintenance positions responsible for implementing specific measures in the SSMP program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation; and
(c) The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the person responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services (OES)).
(iii) Legal Authority: Each Enrollee must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to:
(a) Prevent illicit discharges into its sanitary sewer system (examples may include I/I, stormwater, chemical dumping, unauthorized debris and cut roots, etc.);
State Water Resources Control Board Order No. 2006-0003-DWQ Page 11 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (b) Require that sewers and connections be properly designed and constructed;
(c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency;
(d) Limit the discharge of fats, oils, and grease and other debris that may cause blockages, and
(e) Enforce any violation of its sewer ordinances.
(iv) Operation and Maintenance Program. The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee’s system:
(a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities;
(b) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders;
(c) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long- term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the
condition of sewer pipes and scheduling rehabilitation.

Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan;
(d) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and
State Water Resources Control Board Order No. 2006-0003-DWQ Page 12 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (e) Provide equipment and replacement part inventories, including identification of critical replacement parts.
(v) Design and Performance Provisions :

(b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for
rehabilitation and repair projects.
(vi) Overflow Emergency Response Plan - Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this plan must include the following:
(a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure an appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification;
(d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;
(e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.

State Water Resources Control Board Order No. 2006-0003-DWQ Page 13 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) FOG Control Program: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
(a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
(b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
(c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
(d) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements;
(e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance;
(f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and
(g) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.
(viii) System Evaluation and Capacity Assurance Plan: The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
(a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs State Water Resources Control Board Order No. 2006-0003-DWQ Page 14 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; (b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and
(c) Capacity Enhancement Measures: The steps needed to
establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. (d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update
requirements as described in Section D. 14.
(ix) Monitoring, Measurement, and Program Modifications: The Enrollee shall:
(a) Maintain relevant information that can be used to
establish and prioritize appropriate SSMP activities;
(b) Monitor the implementation and, where appropriate,
measure the effectiveness of each element of the

STATE OF CALIFORNIA

WATER RESOURCES CONTROL BOARD
ORDER NO. WQ 2013 -0058-EXEC

AMENDING MONITORING AND REPORTING PROGRAM
FOR

STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR

SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board) finds:

1. The State Water Board is authorized to prescribe statewide general Waste Discharge Requirements (WDRs) for categories of discharges that involve the same or similar operations and the same or similar types of waste pursuant to Water Code section 13263(i) .

2. Water Code section 13193 et seq. requires the Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) to gather Sanitary Sewer Overflow (SSO) information and make this information available to the public, including but not limited to, SSO cause, estimated volume, location, date, time, duration, whether or not the SSO reached or may have reached waters of the state, response and corrective action taken, and an enrollee's contact information for each SSO event. An enrollee is defined as the public entity having legal authority over the operation and maintenance of, or capital improvements to, a sanitary sewer system gr eater than one mile in length.

3. Water Code section 13271, et seq. requires notification to the California Office of Emergency Services (Cal OES), formerly the California Emergency Management Agency, for certain unauthorized discharges, including SSOs.

4. On May 2, 2006, the State Water Board adopted Order 2006 -0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer Systems" 1 (hereafter SSS WDRs) to comply with Water Code section 13193 and to establish the framework for the statewide SS O Reduction Program.

5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that the Executive Director may modify the terms of the MRP at any time.

6. On February 20, 2008, the State Water Board Executive Director a dopted a revised MRP for the SSS WDRs to rectify early notification deficiencies and ensure that first responders are notified in a timely manner of SSOs discharged into waters of the state.

7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES, pursuant to Water Code section 13271(a)(3), forwards the SSO notification information
2 to local government agencies and first responders including local public health officials and the applicable Regional Water Board. Receipt of notifications for a single SSO event from both the SSO reporter and Cal OES is duplicative. To address this, t he SSO notification requirements added by the February 20, 2008 MRP revision are being removed in this MRP revision.

Monitoring and Reporting Program No. WQ 2013 -0058-EXEC Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 2 of 2

8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the California Water and Environment Association (CWEA), the State Water Board committed to re designing the CIWQS 3 Online SSO Database to allow "event" based SSO reporting versus the original "location" based reporting. Revisions to this MRP and accompanying changes to the CIWQS Online SSO Database will implement this change by allowing for multiple SSO appearance points to be associated with each SSO event caused by a single asset failure.

9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements changes to SSO categories by adding a Category 3 SSO type. This change will improve data management to fu rther assist Water Board staff with evaluation of high threat and low threat SSOs by placing them in unique categories (i.e., Category 1 and Category 3, respectively). This change will also assist enrollees in identifying SSOs that require Cal OES notifica tion.

10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program
4 objectives, assess compliance, and enforce the requirements o f the SSS WDRs.

IT IS HEREBY ORDERED THAT:

Pursuant to the authority delegated by Water Code section 13267(f), Resolution 2002 -0104, and Order 2006 -0003-DWQ, the MRP for the SSS WDRs (Order 2006 -0003-DWQ) is hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

Monitoring and Reporting Program Order No. WQ 2013 -0058-EXEC Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 4 of 12 B. NOTIFICATION REQUIREMENTS
Although Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) staff do not have duties as first responders, this MRP is an appropriate mechanism to ensure that the agencies that have first responder duties are notified in a timely manner in order to protect public health and beneficial uses.

1. For any Category 1 SSO greater than or equal to 1,000 gallons that results in a discharge to a surface water or spilled in a location where it probably will be discharged to surface water, either directly or by way of a drainage channel or MS4, the enrollee shall, as soon as possible, but not later than two (2) hours after (A) the enrollee has knowledge of the discharge, (B) notification is possible, and (C) notification can be provided without substantially impeding cleanup or other emergency measures, notify the Cal OES and obtain a notification control number.

2. To satisfy notification requirements for each applicable SSO, the enrollee shall provide the information requested by Cal OES before receiving a control number. Spill information requested by Cal OES may include:
i. Name of person notifying Cal OES and direct return phone number. ii. Estimated SSO volume discharged (gallons).
iii. If ongoing, estimated SSO discharge rate (gallons per minute). iv. SSO Incident Description:
a. Brief narrative.
b. On-scene point of contact for additional information (name and cell phone number). c. Date and time enrollee became aware of the SSO.
d. Name of sanitary sewer system agency causing the SSO. e. SSO cause (if known).

Following the initial notification to Cal OES and until such time that an enrollee certifies the SSO report in the CIWQS Online SSO Database, the enrollee shall provide updates to Cal OES regarding substantial changes to the estimated volume of untreated or partially treated sewage discharged and any substantial change(s) to known impact(s).

Monitoring and Reporting Program Order No. WQ 2013 -0058-EXEC Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 5 of 12

4. PLSDs: The enrollee is strongly encouraged to notify Cal OES of discharges greater than or equal to 1,000 gallons of untreated or partially treated wastewater that result or may result in a discharge to surface water resulting from failures or flow conditions within a privately owned sewer lateral or from other private sewer asset(s) if the enrollee becomes aware of the PLSD.

C. REPORTING REQUIREMENTS

1. CIWQS Online SSO Database Account: All enrollees shall obtain a CIWQS Online SSO Database account and receive a “Username” and “Password” by registering through CIWQS.

These accounts allow controlled and secure entry into the CIWQS Online SSO Database.

2. SSO Mandatory Reporting Information: For reporting purposes, if one SSO event results in multiple appearance points in a sewer system asset, the enrollee shall complete one SSO report in the CIWQS Online SSO Database which includes the GPS coordinates for the location of the SSO appearance point closest to the failure point, blockage or location of the flow condition that caused the SSO, and provide descriptions of the locations of all other discharge points associated with the SSO event.

3. SSO Categories
i. Category 1 – Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:
a. Reach surface water and/or reach a drainage channel tributary to a surface water; or b. Reach a MS4 and are not fully captured and returned to the sanitary sewer system or not otherwise captured and disposed of properly. Any volume of wastewater not recovered from the MS4 is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or groundwater infiltration basin (e.g., infiltration pit, percolation pond). ii. Category 2 – Discharges of untreated or partially treated wastewater greater than or equal to 1,000 gallons resulting from an enrollee’s sanitary sewer system failure or flow condition that does not reach a surface water, a drainage channel, or the MS4 unless the entire SSO volume discharged to the storm drain system is fully recovered and disposed of properly. iii. Category 3 – All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition.

4. Sanitary Sewer Overflow Reporting to CIWQS - Timeframes i. Category 1 and Category 2 SSOs – All SSOs that meet the above criteria for Category 1 or Category 2 SSOs shall be reported to the CIWQS Online SSO Database:
a. Draft reports for Category 1 and Category 2 SSOs shall be submitted to the CIWQS Online SSO Database within three (3) business days of the enrollee becoming aware of the SSO. Minimum information that shall be reported in a draft Category 1 SSO report shall include all information identified in section 8.i.a. below. Minimum information that shall be reported in a Category 2 SSO draft report shall include all information identified in section 8.i.c below.

Monitoring and Reporting Program Order No. WQ 2013 -0058-EXEC Statewide Waste Discharge Requirements for Sanitary Sewer Systems Page 6 of 12 b. A final Category 1 or Category 2 SSO report shall be certified through the CIWQS Online SSO Database within 15 calendar days of the end date of the SSO. Minimum information that shall be certified in the final Category 1 SSO report shall include all information identified in section 8.i.b below. Minimum information that shall be certified in a final Category 2 SSO report shall include all information identified in section 8.i.d below.
ii. Category 3 SSOs – All SSOs that meet the above criteria for Category 3 SSOs shall be reported to the CIWQS Online SSO Database and certified within 30 calendar days after the end of the calendar month in which the SSO occurs (e.g., all Category 3 SSOs occurring in the month of February shall be entered into the database and certified by March 30). Minimum information that shall be certified in a final Category 3 SSO report shall include all information identified in section 8.i.e below. iii. “No Spill” Certification – If there are no SSOs during the calendar month, the enrollee shall either 1) certify, within 30 calendar days after the end of each calendar month, a “No Spill” certification statement in the CIWQS Online SSO Database certifying that there were no SSOs for the designated month, or 2) certify, quarterly within 30 calendar days after the end of each quarter, “No Spill” certification statements in the CIWQS Online SSO Database certifying that there were no SSOs for each month in the quarter being reported on. For quarterly reporting, the quarters are Q1 - January/ February/ March, Q2 - April/May/June, Q3 - July/August/September, and Q4 - October/November/December.

If there are no SSOs during a calendar month but the enrollee reported a PLSD, the enrollee shall still certify a “No Spill” certification statement for that month. iv.

Parkway Tree Root Intrusion Into Sewer Lateral ‐ Policy and Procedures Section 14.54.035 of the City of Huntington Beach Municipal Code addresses responsibilities for the operation, maintenance and repair of sewer laterals. The City is responsible for the maintenance and repair of the portion of the sewer lateral within the public right‐of‐way that extends from the City‐owned sewer main to the private property line.

The property owner is responsible for the repair and maintenance of the portion of the sewer lateral located on private property.

Reminder‐ liquid grease solidifies as it travels from your sink to the collection system down‐stream and many items such as baby wipes, feminine hygiene products, eggshells and coffee grounds should not be flushed.

Sewer Lateral Program Procedure:

1. A property owner experiencing problems* with the sewer lateral calls the Public Works Utilities Division at (714) 536‐5921, to notify them of the problem.

2. The property owner secures the services of a qualified contractor to clean and video tape the interior of the sewer
lateral from the house cleanout to the public sewer main. While cleaning and/or video taping the lateral, it is important for the contractor to locate and mark the actual sewer lateral location at the property line, on the sidewalk, at the curb and at the connection with the sewer main. The use of water soluble spray paint to show the location of the sewer lateral is highly recommended as laterals are often at different angles and locations than portrayed on many record drawings.

3. The property owner submits a copy of the video to the Utilities Division staff at 19001 Huntington Street between the hours of 7:00 AM and 4:30 PM, Monday through Friday.

4. The Utilities Division staff will review the video to determine the cause of the blockage, if and what type of repair is needed and whether the location of the blockage and repair are within the City’s right‐of‐way.

5. Depending on the situation, there are typically two options for repair: 1) Slip Lining the sewer lateral within the public right‐of‐way and on the private property leaving the parkway tree intact. In this case, the city arborist needs to determine that the integrity of the tree will
not be impacted by the repairs made to the sewer lateral. The property owner is responsible for the cost of slip lining the sewer lateral on their private property. 2) In a case where it is determined that the tree must be removed to complete the repair, and it falls within the City’s responsibility, the City will initiate repairs at the City’s cost and reimburse the cost of the video to the property owner.

Questions regarding the Sewer Lateral Program should be directed to the Public Works Utilities Division at (714) 536‐5921. This information can also be reviewed at the City’s website: www.surfcity‐hb.org *The first course of action for a blocked or clogged sewer line is a call to a qualified plumber or sewer contractor. Often times, cleaning of the line is needed immediately and residents should not wait for the claim process to be completed.

The need for frequent cleaning/rooting of the line is an indication of a possible sewer lateral break or tree root intrusion.

SEWER SYSTEM CAPACITY ANALYSIS

EXECUTIVE SUMMARY

ES-1 Introduction

The City of Huntington Beach’s Sewer Master Plan was completed in May 2003. The Master Plan conducted a capacity analysis of the collection system and determ ined that out of approximately 360 miles of sewer reaches, only several reaches were found deficient ba sed on the model results and criteria. The calculated deficiencies are based upon somewhat conservative unit fl ow factors and peaking relationships. Therefore it is prudent to verify the calculated deficiencies before investing in replacement or relief projects. The objective of this study is to conduct flow monitoring along the reaches that were identified as deficient by the 2003 Sewer Master Plan in order to ascertain whether a deficiency exists, and to provide recommendations for eliminating the verified deficiencies.

ES-2 Criteria
Sewer Design Criteria

The 2003 Master Plan analysis of sewer pipes was bas ed upon the depth to diameter ratio (d/D), resulting from peak dry weather flows. The criteria used for the 2003 Master Plan are as follows:

- Depth to diameter ratio (d/D) less than or equal to 0.5 for pipes 12-inch and smaller in diameter - d/D less than or equal to 0.67 for 15-inch diameter pipes - d/D less than or equal to 0.75 for 18-inch diameter and larger pipes

Reaches that do not satisfy the City’s d/D criteria ar e considered deficient and require additional capacity analyses.

The 2003 Master Plan flow depths were calculated utiliz ing estimated peak dry weather flows. Average dry weather flows, which are calculated based upon the pr oduct of the tributary land use areas and unit flow factors, and a peaking relationship were used to estimate the peak dry weather flows.

The depth of flow and design capacity of gravity pipe s were calculated based on the Manning formula with a friction factor (Manning’s n) of 0.013.

ES-3 Existing System

The 2003 Sewer Master Plan identified nine (9) areas as deficient, which are listed in Table ES1. The locations of the deficient reaches are shown in Appendix A.

Flow Monitoring Locations

The flow monitoring locations were chosen to analyze the capacity deficient sewers that were identified in the 2003 Sewer Master Plan. Extensive flow monitoring near the Edinger Lift Station was required to analyze the effects the pumped flows have on the existing sewer system.

Initially, eleven (11) sites were select ed for flow monitoring. Flow monitors were installed at nine (9) of the eleven (11) sites. Data was collected between 12:00 A. M. June 14, 2007 and 11:45 P.M. June 27, 2007.

Two (2) additional flow monitoring sites were selected and monitors were installed between 12:00 A.M.

January 16, 2008 and 11:45 P.M. February 5, 2008 to analyze the flows with the improved Edinger Lift Station. The flow monitoring results are summarized in Table ES2.

2003 Sewer Master Plan Data

The City’s 2003 Sewer Master Plan used the following peaking relationship to develop the peak dry weather flow (Qpdw) from the average dry weather flow (Qadw):

Qpdw = 1.93(Qadw)0.898

SEWER SYSTEM CAPACITY ANALYSIS
ES-3 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis This relationship was evaluated with the use of the flow monitoring data, maintaining the exponent 0.898.

Flow Monitoring Sites No.’s 4, 7, 8, 11, and 12 we re excluded from this analysis because they are downstream of lift stations. The coefficient used in the Master Plan (1.93) is higher than the values calculated from the flow monitoring data, which average approxim ately 1.60. Therefore, the peak dry weather flow estimates used in the 2003 Master Plan were conservative, which is appropriate for planning level studies.

Capacity Analysis and Recommendations
During the initial field verification at Flow Monitoring Site No. 2, the field crew rea lized that the Sewer Master Plan Deficiency No. 2 was no longer in existence. The Orange County Sanitation District installed a 30-inch diameter trunk sewer on Heil Avenue, and the City was able to divert its wastewater dire ctly into this facility.

This also allowed the City to abandon the sewers on Heil Avenue from Torjian Lane to Oakmont Lane, and on Edwards Street from Heil Avenue to Brad Drive. Defi cient Location No. 2 was part of these abandoned pipes and does not require further analysis.

Assuming that the normal maximum flow recordings from the flow monitoring effort represent the peak dry weather flows, the flow monitoring results were analyzed based on the 2003 Sewer Master Plan criteria.

• Sewer Master Plan Deficiency No.’s 1 and 3 meet the existing depth to diameter (d/D) criteria and are not recommended to be replaced for capacity.

• Deficiency No.’s 4 and 9 do not satisfy the City’s d/D criteria. However, these deficiencies are minor and do not warrant replacement of the existing pipes for capacity. If the tributary land use is proposed to be changed significantly in the future, resulting in higher wastewater flows, then these reaches should be re-evaluated.

• The flow monitoring measurements at Sewer Master Plan Deficiency No. 5 show a maximum depth to diameter ratio of 0.78. Based on a pipe slope of 0.002 and Manning’s n of 0.013, the Master Plan estimated that the ultimate peak dry weather fl ow would require a minimum pipe diameter of 15 inches to meet the City’s depth to diameter design criteria of 0.67. These reaches will require further evaluation by the City.

• At Sewer Master Plan Deficiency No. 6, the flow monitoring shows the four reaches of sewer pipes flowing at a maximum depth to diameter ratio of 0.77. Based on the record slope of 0.002, Manning’s n of 0.013 and the ultimate peak dry weather flow, the existing sewers would require a minimum pipe diameter of 15 inches to meet the City’s depth to diameter criteria of 0.67. These reaches will require further evaluation by the City.

• Sewer Master Plan Deficiency No. 7 is downstream of the Saybrook Lift Station, which is scheduled to be replaced in the next 3 to 8 years. The flow monitoring shows the reach flowing at a depth to diameter ratio of 0.59, which does not meet the City’s criteria. Based on a slope of 0.002, Manning’s n of 0.013 and the anticipated Saybrook Lift Stati on discharge of 826 gpm, a minimum pipe diameter of 15 inches in needed to meet the City’s depth to di ameter design criteria of 0.67. This reach will require further evaluation by the City when the Saybrook Lift Station is improved.

• The Edinger Lift Station underwent improvements du ring the recent sewer capacity analysis. Sewer Master Plan Deficiency No. 8 is downstream of th is lift station and required additional analysis, which

SEWER SYSTEM CAPACITY ANALYSIS
ES-4 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis included flow monitoring before and after the pump station improvements were completed as well as pump capacity tests at the Edinger Lift Station. T he flow monitoring performed after the Edinger Lift Station was replaced indicated maximum flow rates of 500 gpm. Pump capacity tests conducted in May 2008 estimated similar flows of 510 gpm. Based on this flow rate, the record slope of 0.002, and Manning’s n of 0.013, a minimum pipe diameter of 15 inches would be necessary to meet the City’s depth to diameter criteria of 0.67 for the ten (10) reaches identified as deficient in the 2003 Sewer Master Plan. During the Edinger Lift Station pump capacity testing, the existing peak inflow into the lift station was measured as 285 gpm. To reduce the depth to diameter ratio in the ten (10) downstream sewers, the City may decrease the pump capacity from 500 gpm to 400 gpm. In doing so, approximately 37% of the ultimate PDWF w ill remain available for wet weather inflow and infiltration. By reducing the flow to 400 gpm, the downstream sewers are expected to flow at a depth to diameter ratio of approximately 0.744.

• The 2003 Sewer Master Plan identified three (3) “Bor derline” deficient reaches just downstream of Deficiency No. 8. During the master planning effo rt, “Borderline conditions” were the reaches that had calculated d/D values which were close to the deficiency criteria d/D values, but were not determined “Deficient” by engineering judgment. Fo r this current analysis, these reaches were evaluated with the relevant Edinger Lift Station flow monitoring data. While the d/D ratios for these reaches were 0.59, which is deficient according to the master plan standards, it does not warrant replacement of the existing pipes for capacity. If the tributary land us is proposed to be changed significantly in the future, resulting in higher wastewater flows, then these reaches should be reevaluated.

SEWER SYSTEM CAPACITY ANALYSIS

1-1 Introduction

The City of Huntington Beach’s Sewer Master Plan was completed in May 2003. The Master Plan conducted a capacity analysis of the collection system utilizing a computer hydraulic model. Out of approximately 360 miles of sewer reaches, only a few reaches (less than 0.6 percent) were determined to be deficient. The calculated deficiencies are based upon somewhat conser vative unit flow factors and peaking relationships.

Therefore it is prudent to verify the calculated deficiencies before investing in replacement or relief projects.

The objective of this study is to conduct flow monitori ng along the reaches that were identified as deficient by the 2003 Sewer Master Plan in order to ascertai n whether a deficiency exists, and to provide recommendations for eliminating the verified deficiencies.

1-2 Criteria
The 2003 Sewer Master Plan generated the average dry weather flows by summing the product of tributary land uses and their corresponding unit flow factors. The land use was designated based on the general plan.

The flow factors were created using the flow monitoring results as well as previous studies.

The adequacy of a sewage collection system is based upo n its ability to convey the peak flows. At any individual point in the system, peak dry weather flow (P DWF) is estimated by converting the total average dry weather flow upstream of the point in question to p eak dry weather flow by an empirical peak-to-average relationship.

The peaking relationship used in preparing the 2003 Master Plan was developed based upon the flow monitoring conducted at 12 locations throughout the City.

Q
pdw = 1.93(Qadw)0.898
Flowrates are in million gallons per day (mgd).

Sewer Design Criteria

Design criteria are established to ensure that the sewer system can operate effectively under all flow conditions. Each sewer reach must be able to carry peak wet weather flows without surcharging the system.

Low flows must be conveyed at a velocity that will prevent solids from settling and blocking the system.

The design and analysis of sewer pipes were based upon the depth to diameter ratio (d/D), resulting from peak dry weather flows. The criteria used for the 2003 Master Plan are as follows:

Depth to diameter ratio (d/D) less than or equal to 0.5 for pipes 12-inch and smaller in diameter

d/D less than or equal to 0.67 for 15-inch diameter pipes

d/D less than or equal to 0.75 for 18-inch diameter and larger pipes

SEWER SYSTEM CAPACITY ANALYSIS
1-2 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis The remaining area above the maximum dry weather flow depth is primarily reserved for the selected design wet weather flows; however, this space also keeps the sewage aerated which reduces the possibility of septic conditions and odors.

The 2003 Master Plan flow depths were calculated based on peak dry weather flows.

The design capacity of gravity pipes is calculated based on the Manning formula:

Q = 1.486 A R
2/3 S1/2 / n
Q = flow in cubic feet per second
R = hydraulic radius in feet = A / P
A = cross-sectional area of the pipe in square feet
P = wetted perimeter in feet
S = slope of pipe in feet of rise per foot of length
n = Manning’s friction factor (n=0.013 was used fo r vitrified clay pipe in the 2003 Master Plan)

The peak flow velocity should be greater than 2 feet per second to prevent deposition of solids in the pipe.

1-3 Existing System

The City’s existing sewer collection system is made up of a network of gravity sewers, consisting of approximately 360 miles of pipe, and twenty-nine (29) sewer lift stations.

The general direction of flow is from north to south and we st to east. The majority of the City sewers tie into the Orange County Sanitation District (OCSD) trunk sewers for conveyance to the local treatment plant.

The sewers are primarily constructed of vitrified clay pipe with sizes ranging from 6-inches to 30-inches in diameter. Approximately 85 percent of the pipes are 8-inches in diameter.

The 2003 Sewer Master Plan identified nine (9) areas as deficient, which are listed in Table 1. The locations of the deficient reaches are shown in Appendix A.

SEWER SYSTEM CAPACITY ANALYSIS
1-3 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis There are four (4) sewer lift stations that are upstream of the identifi ed deficient sewer pipes. Speer Lift Station (LS No. 20) affects Deficient Location No. 4; Saybrook Lift Station (LS No. 22) affects Deficient Location No. 7; Edinger Lift Station (LS No. 25) affects Deficient Location No.’s 8 and 9; and Trinidad Lift Station (LS No. 29) affects Deficient Location No. 9.

Speer Lift Station (LS No. 20) is located at Speer Avenue and Crabb Lane. It has two (2) Wemco 6 x 11 pumps with 9-inch impellers. Each pump has a ra ted capacity of 400 GPM at 14 foot total dynamic head (TDH). The 2003 Sewer Master Plan estimated t he peak dry weather flow at 300 gpm, and did not recommend any capacity improvement at this lift station.

Saybrook Lift Station (LS No. 22) is located on Saybrook Avenue, north of Heil Avenue. It has two (2) Wemco 4 x 11 M pumps with 9.75-inch impellers. Each pump has a rated capacity of 550 GPM at 23 foot TDH. The estimated ultimate peak dry weather flow is 739 gp m. The 2003 Sewer Master Plan recommended that the firm capacity of this pump station be increased to 1,000 gpm to accommodate the peak wet weather flows.

Firm capacity is the total pumping capacity at the lift station when the largest pump is not in operation.

The Edinger Lift Station (LS No. 25) is located on Edinger Avenue and Santa Barbara Drive. According to the 2003 Sewer Master Plan, the estimated ultimate peak dr y weather flow is 423 gpm. Prior to the recent improvements, the lift station had two (2) Wemco 4 x 11 M pumps with 8-inch impellers. These pumps were rated at 300 GPM capacity and 12 foot TDH. Recent improvements incr eased the design capacity of the Edinger Lift Station pumps from 300 gpm to 400 gpm each. It currently contains two (2) Wemco 4 x 11 S pumps with 8.5-inch impellers. As shown in Tables 16 and 17, the flow monitoring conducted in January and February 2008 indicated that the flows recorded at Site No.’s 8 and 12 respectively, are notably higher than the improved pump station design capacity. Further te sting at the pump station wa s performed to verify the actual pumping capacity, as detailed in Section 1-4. The downstream sewer facilities were analyzed based upon the actual pump capacities.

Trinidad Lift Station (LS No. 29) is located on Trinidad Lane and Aquarius Drive. It has two (2) Wemco 4x11M pumps with 8-inch impellers. Each pump is rated at 250 gpm and 15 foot TDH. The estimated ultimate peak dry weather flow is 153 gpm. Since the existing firm capacity is greater than the expected peak wet weather flow, the 2003 Sewer Master Plan did not recommend any capacity improvement at this lift station.

1-4 System Analysis

Flow Monitoring Locations

The flow monitoring locations were chosen to analyze the capacity deficient sewers that were identified in the 2003 Sewer Master Plan. Ideally, the flow monitoring locations would have smooth flows with sufficient depth and velocity that could be detected by the flow monitori ng equipment. Manholes with multiple inflow pipes or sharp turns are generally avoided because the turbulent flows cannot be accurately measured by the flow monitors.

Extensive flow monitoring near the Edinger Lift Statio n was required to analyze the effects the pumped flows have on the existing sewer system.

Initially, eleven (11) sites were select ed for flow monitoring. Prior to the installation of the flow monitoring equipment, field verifications were made on June 6, 2007 to ensure that the locations would provide useful data. Following the review of Flow Monitoring Site No. 2 at Edwards Street and Brad Drive, the field crew realized that the study sewer no longer exists at the location. The 2003 Sewer Master Plan shows that there are three (3) manholes on Edwards Street, between Brad Drive and Heil Avenue. The field crew could not locate any of these manholes. The inspection of the manhole at the intersection of Edwards Street and Brad Drive shows that the inlet pipe from the north had been blocked off, as shown on Figure 1.

SEWER SYSTEM CAPACITY ANALYSIS
1-5 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis The Orange County Sanitation District installed a 30” diameter trunk sewer on Heil Avenue. The City was able to divert its wastewater directly into this OCSD facility at the intersection of Heil Avenue and Torjian Lane from the southwest and at the intersection of Heil Avenue and Oakmont Lane from the northeast. In doing so, the City abandoned the sewers on Heil Avenue from Torjian Lane to Oakmont Lane and on Edwards Street from Heil Avenue to Brad Drive. Since the sewe rs at Deficient Location No. 2 are included in this abandoned pipe set, there will be no need for improvements.

Furthermore, while reviewing the flow monitoring Si te No. 9 at Edinger Avenue and Santa Barbara Lane, the field crew became aware that the Edinger Lift Station was undergoing construction. The sewers that are upstream of the Edinger Lift station were inaccessible due to the construction of the improvements.

Therefore, flow monitoring at Site No. 9 was not possible.

Following the field verification, nine (9) flow monitoring sites were selected for the capacity analysis study.

The improvements to the Edinger Lift Station were finalized after the initial flow monitoring was completed.

Since the new pumps have higher capacities, further fl ow monitoring was required to accurately evaluate the capacity of the downstream sewer reaches with the new pumps. Flow monitoring was performed between January 16, 2008 and February 5, 2008 at two locations. One flow monitor was installed at Site No. 8, and another was installed at Saybrook Lane and Fisher Driv e (Site No.12). The initial and additional flow monitoring data at Site No. 8 will be utilized throughout this report for various purposes; however, the final recommendations are based on the most recent flow monitoring data which reflect the current sewer system.

General Flow Monitoring Results

The initial flow monitors were installed and data was collected between 12:00 A.M. June 14, 2007 and 11:45 P.M. June 27, 2007. Subsequent flow monitoring wa s performed between 12:00 A.M. January 16, 2008 and 11:45 P.M. February 5, 2008. Flow vs. time graphs ar e located in Appendix C. The flow monitoring results are summarized in Table 3.

As described in the criteria section, the City’s 2003 Sewer Master Plan used the following peaking relationship to develop the peak dry weather flow (Qpdw) from the average dry weather flow (Qadw):

SEWER SYSTEM CAPACITY ANALYSIS
1-7 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis Qpdw = 1.93(Qadw)0.898
This relationship was evaluated with the use of the flow monitoring data, maintaining the exponent 0.898.

Flow Monitoring Sites No.’s 4, 7, 8, 11, and 12 we re excluded from this analysis because they are downstream of lift stations. This review shows that the coefficient used in the Master Plan (1.93) is higher than the values calculated from the flow monitoring data, as shown in Table 6. Therefore, the peak dry weather flows calculated by the Master Plan are estima ted conservatively, which is appropriate for planning studies.

Capacity Analysis and Recommendations

The hydraulic analysis for the 2003 Sewer Master Plan is included in Appendix D. It includes the calculated existing peak dry weather flow and the ultimate peak dry weather flow.

Deficient Location No. 1

This location includes six (6) reaches of 18-inc h diameter sewer located on Hamilton Avenue, from Brookhurst Street to Archer Circle with a total length of 1,530 feet. The flow monitor was installed in Pipe 1014, upstream of the manhole between Pipes 1013 and 1014. This location is near the downstream end of the deficient pipe, with nearly the largest tributary ar ea of the six segments. The comparison of the flow monitoring data and the 2003 Sewer Master Plan data is shown in Table 7.

Master Plan Data Data Flow Monitoring Data

With the Master Plan calculated peak dry weather flows, four (4) of the six (6) reaches would flow full, and the depth to diameter ratio would exceed 0.75 in the other two reaches. The Site 1 flow monitor recorded average dry weather flow, peak dry weather flow, and depth values that are much lower than those calculated by the Sewer Master Plan. The Sewer Master Plan average dry weather flow (795 gpm) is larger than the flow monitoring average dry weather flow (520 gpm) by a fact or of 1.5. The Sewer Master Plan peak dry weather flow (1,514 gpm) is larger than the flow monitoring peak dry weather flow (907 gpm) by a factor of 1.7.

According to the flow monitoring data, this 18” sewer is flowing at a d/D of 0.52, which is considered sufficient.

The sewers in this location are not recommended to be replaced for capacity. If the tributary land use is proposed to be changed in the future resulting in hi gher wastewater flows, these sewers should be re- evaluated.

Deficient Location No. 2

Appendix D of the 2003 Sewer Master Plan shows that the ultimate d/D’s for the reaches of sewer on Edwards Street from Heil Avenue to Brad Drive and on Heil Avenue from Oakmont Lane to Edwards Street were calculated from 0.67 to full, which is deficient according to the master plan criteria. When these sewers were reviewed in the field for selecting flow monitori ng locations, the field crew concluded that the sewer on Edwards Street was removed because the City sewers upstream have been diverted to the OCSD’s trunk sewer on Heil Avenue. The OCSD records show that the City facilities have been diverted to the OCSD trunk sewer on Heil Avenue at Torjian Lane and Heil Avenue at Oakmont Drive. The 2003 Master Plan indicates that none of these pipes are on the City’s Sewer GIS.

Deficient Location No. 3

The 2003 Sewer Master Plan identified capacity deficien cies in three (3) reaches of 12-inch diameter pipe located on Heil Avenue between Sabot Lane on the east and Goldenwest Street on the west. With the master plan calculated peak dry weather flows, the d/ D’s of these three (3) reaches are approximately 0.68, which is deficient per the master plan criteria. The total length of these reaches is approximately 830 feet.

The flow direction is from east to west. The flow monitor was installed in Pipe 295, upstream of the manhole between Pipes 294 and 295. It measures nearly the entire flow tributary to the most downstream pipe. The comparison between the flow monitoring data and the 2003 Sewer Master Plan data is shown in Table 8.

Master Plan Data Data Flow Monitoring Data

The Pipe 294 data is missing the slope value in the Mast er Plan. However, this value can be estimated as

0.002, which is representative of the slopes for the nearby pipes. The 2003 Sewer Master Plan estimates a depth to diameter ratio of 0.55 for all three reaches of 12” pipe. According to the 2003 Sewer Master Plan Criteria, these pipes are considered deficient. Ho wever the average dry weather flow from the flow monitoring (149 gpm) was lower than the calculated 2003 Sewer Master Plan existing average dry weather flow (186 gpm). Likewise, the peak dry weather flow from the flow monitoring (256 gpm) was far lower than the calculated 2003 Sewer Master Plan existing peak dry w eather flow (411 gpm). The flow monitoring data shows that these pipes are flowing at a depth to diameter ratio of about 0.46 with the actual peak dry weather flows. Therefore, these reaches of pipe are currently sufficient per the 2003 Sewer Master Plan criteria, and are not recommended to be replaced for capacity. The 2003 Sewer Master Plan shows the ultimate peak dry weather flow at 579 gpm, an increase of nearly 41 percent. Based upon review of the aerial photographs, the tributary area does not seem to include significant vaca nt land. However, assuming a similar increase over the existing flows, the peak dry weather flow woul d be 354 gpm, and the depth to diameter ratio would be approximately 0.5, which is still sufficient. If the tribut ary land use is proposed to be changed in the future resulting in higher wastewater flows, then these reaches should be re-evaluated.

Deficient Location No. 4

The 2003 Sewer Master Plan identified capacity deficiencies in six (6) reaches of 8-inch diameter sewer on Speer Avenue between Jacquelyn Lane to the west and Be ach Boulevard to the east. With the master plan calculated peak dry weather flows, these six (6) reaches will flow full. The total length of these reaches is approximately 1,365 feet. The flow direction is from west to east. These reaches convey the wastewater flow pumped by Speer Lift Station (LS No. 20), which is lo cated at Crabb Lane and Speer Avenue, as well as the wastewater collected from the tributary area to the east of the lift station.

The flow monitor was installed in Pipe 545, upst ream of the manhole between Pipes 545 and 548. It measures nearly the entire flow tributary to the most downstream reach of the deficient sewers. The comparison between the flow monitoring data and the 2003 Sewer Master Plan data is shown in Table 9.

Master Plan Data Data Flow Monitoring Data

The 2003 Sewer Master Plan estimates peak dry weather flows of over 500 gpm near the pump station, and 449 gpm at the most downstream reach. All six r eaches of pipe would flow full with the Master Plan estimated flows. However, the average dry weather fl ow from the flow monitoring (41 gpm) is approximately 25 percent of the Master Plan flows. The peak dry weathe r flow from the flow monitoring (140 gpm) is also approximately 25 percent of the Mast er Plan flows and the reported pump capacity of 500 gpm. Available aerial photography shows the lift station tributary area to be industrial. The flow monitoring results are clearly of an industrial land use with week end flows significantly lower than t he weekday flows. The discrepancy between the measured and calculated fl ows is most likely due to the high industrial unit flow factors used in the Master Plan, and the selected peaking relationshi p. The discrepancy between the reported pump capacity and measured flows may be due to the att enuation in the gravity pi pe system, infrequent pump operation, and short duration of pumping. The tributary area is fully developed, and the ultimate flows are not expected to be greater than the existing flows.

The flow monitoring data shows that these pipes are fl owing at a maximum depth to diameter ratio of 0.54.

While this is deficient per the City’s criteria, it does not warrant replacement of the existing pipes for capacity.

If the tributary land use is proposed to be changed signifi cantly in the future, resulting in higher wastewater flows, then these reaches should be re-evaluated.

Deficient Location No. 5

The 2003 Sewer Master Plan identified capacity deficienc ies in two (2) reaches of 12-inch diameter sewer on Beach Boulevard between Speer Avenue to the south and Sl ater Avenue to the north. With the master plan calculated peak dry weather flows, both reaches will flow full. The total length of these reaches is 657 feet and the flow direction is from south to north. The De ficient Location No. 4 flows, including the Speer Lift Station are tributary to this area.

The flow monitor was installed in Pipe 547, upst ream of the manhole between Pipes 531 and 547. It measures nearly the entire flow tributary to the most downstream reach of the deficient sewers. The comparison between the flow monitoring data and the 2003 Sewer Master Plan results is shown in Table 10.

Master Plan Data Data Flow Monitoring Data

The 2003 Sewer Master Plan estimates existing peak dry weather flows of about 912 and 914 gpm in the two reaches of pipe. Both of these reaches would flow full with the Master Plan estimated flows. The average dry weather flow from flow monitoring (284 gpm) is a pproximately 63 percent of the Master Plan estimated existing flow. Likewise, the peak dry weather flow fr om the flow monitoring (508 gpm) is approximately 56 percent of the Master Plan estimated existing flows. The Master Plan es timates only a 3.9 percent increase in the average dry weather flows and 3.5 percent increa se in the peak dry weather flows with the ultimate development of the tributary area. The discrepancy between the estimated and measured flows is most likely due to the high industrial unit flow factors, and the peaking relationship used in the Master Plan.

The 2003 Sewer Master Plan estimated peak dry weather flow exceeds the capacity of the pipe, and both pipes would flow full under these conditions. The flow monitoring data shows a maximum depth to diameter ratio of 0.78. Based upon a pipe slope of 0.002, and Manning’s n of 0.013, the Master Plan estimated that the ultimate peak dry weather flow would require a minimum pipe diameter of 15 inches to meet the City’s depth to diameter design criteria of 0.67. These reaches will require further evaluation by the City.

Deficient Location No. 6

The 2003 Sewer Master Plan identified deficiencies in tw o (2) reach of 8-inch and two reaches of 10-inch diameter sewer on Beach Boulevard between south of Talbert Avenue to the south and Ronald Road to the north. With the master plan calculated peak dry weather flows, two (2) of the four (4) reaches flow full and the d/D’s exceed 0.66 in the other two (2) reaches. The total length of the four reaches is 1,086 feet. The flow direction is from south to north.

The flow monitor was installed in Pipe 598, upst ream of the manhole between Pipes 590 and 598. It measures nearly the entire flow tributary to the most downstream reach of the deficient sewers. The comparison between the flow monitoring data and the 2003 Sewer Master Plan results is shown in Table 11.

K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis The Pipe 590 data is missing the slope value in the 2003 Sewer Master Plan. However, this value can be estimated as 0.002, which is representative of the slopes for the nearby pipes. The 2003 Sewer Master Plan estimates existing average and peak dry weather flow of 149 gpm and 336 gpm respectively in Pipe 598. The average dry weather flow from flow monitoring (234) is approximately 57 percent higher than the Master Plan estimated existing average dry weather flow. The peak dry weather flow from flow monitoring (431 gpm) is approximately 28 percent higher than the Master Plan estimated existing peak dry weather flow. The discrepancy between the measured and estimated flows may be due to the presence of some high water users in the tributary area. A detailed study of the water use in the tributary area should be conducted to identify the reason for the difference. The Master Pl an estimates only a 7.3 percent increase in the average dry weather flows with the ultimate development of the tributary area. Applying the same increase to the measured flows, the ultimate peak dry weather flow would be 460 gpm.

The flow monitoring shows these pipes flowing at a depth to diameter ratio of 0.77. Based on the slope of

0.002, Manning’s n of 0.013 and the ultimate peak dry w eather flow of 460 gpm, the four (4) existing sewers would require a minimum pipe diameter of 15 inches to m eet the City’s depth to diameter design criteria of

0.67. These reaches will require further evaluation by the City.

Site No.’s 7, 8, 10, 11, and 12 - Flow Monitoring Sites No.’s 8, 10, 11, and 12 are tributary to Flow Monitoring Site No. 7. These five flow monitoring sites will be described together for clarity. The flow pattern is shown on Figure 2.

Since the flow monitoring sites are tributary to one another; a variation at one site could affect all of the sites.

Prior to the installation of the flow monitors, it was understood that the Edinger Lift Station (Lift Station No. 25) was undergoing replacement. During the period when the flow monitors were initially installed (June 14, 2007 to June 28, 2007), the City ran tests on this lift station. These tests might have altered the initial results at Flow Monitoring Sites No.’s 7, 8, and 11. To analyze the flow monitoring data at these three unique sites, the flow monitoring must be done simultaneously. Therefore, the Site No. 8 flow monitoring data described hereon will refer to the initial flow monitoring that took place in June 2007. The flow monitoring at Site No. 8 performed in January, 2008 will be analyzed later.

The Edinger Lift Station underwent testing at roughly 10:30 AM on July 14, 2007. According to Dudek Engineering, the existing lift station (before capacity improvements) was temporarily shut down to test the capacity of the new pumps. The SCADA data at the Edi nger Lift Station, illustrated on Figure 3, shows that the existing pumps were not in operation at 10:30 A.M.

According to the City, the flow was diverted around the Edinger Lift Station during this period. The flow data does not reflect normal operating conditions.

The increased flows during the Edinger Lift Station test ing must be analyzed in further detail before analyzing the downstream sewer lines. During these two periods, the Site No.’s 7, 8 and 11 flow monitors recorded abnormally high flow rates. These abnormalities can be seen on the flow versus time graphs for these sites in Appendix C. These high flow rates are more representative of the improved pump station conditions, not the conditions during that time period. The additional flow monitoring was performed at Site No. 8 and Site No. 12 following the completion of the improvement to the Ed inger Lift Station (LS No. 25) in order to analyze the capacity of the downstream system.

Prior to the improvements, each pump at the Edinger Lift Station had a design capacity of roughly 225 gpm.

With both pumps running, the lift st ation has a capacity of about 450 gpm. The 2003 Sewer Master Plan calculated the existing PDWF at the Edinger Lift Station at 415 gpm. The pumped flow was measured at Site No. 11, which is directly downstream of the existing lift station. Not including the high flow values related to the pump station testing, the peak dry weather flows were measured to be roughly 460 gpm during the initial flow monitoring. These various flows are consistent and are representative of t he Edinger Lift station flows before the improvements were completed.

The existing pumps at the Edinger Lift Station were designed for a capacity of 400 gpm. Under normal circumstances, one pump will be in operation. The pumps current ly alternate to avoid wear-and-tear on one single pump. However, during extreme wet weathe r conditions and/or emergencies, both pumps may be required to operate simultaneously when the wet well level exceeds the maximum set level. The results at the downstream Flow Monitoring Sites No. 8 and 11 exhi bited flows that are great er than what the pumps were designed for. The maximum daily flows at thes e flow monitoring sites were frequently greater than 500 gpm, which is higher than what was expected if the Ed inger Lift Station were in operation with one pump at a capacity of 400 gpm. During the flow monitoring period, the Edinger Lift Station required both pumps to run

K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis simultaneously on only one occasion, which occurred when wastewater accumulated in the wet well during a power outage.

Since the measured flows from the flow monitoring study were considerably higher than the design pump capacity, pump tests were performed to verify the act ual capacity of the pumps. The testing was performed when the wastewater flows were expected to be larges t. The City crew informed AKM Consulting Engineers that the testing should be performed at approximately 7:00 a.m., which is when the City generally observes peak dry weather flows. The tidal affects on the inflow to the lift station were also taken into consideration.

The different tide levels affect the groundwater levels, which contribute to the amount of infiltration into the wastewater system. Since the Edinger Lift Station tri butary area is adjacent to the Pacific Ocean, a tide analysis was conducted before performing the pump tests.

The average daily flows from the rec ent Flow Monitoring Sites No. 8 and 12 were analyzed with the daily tide history during the same period. It was concluded t hat larger average day flows occurred approximately 5 days after a spring tide, which is when a tide’s range is at a maximum. The tide tables showed that the next spring tide occurred on May 5, 2008. The Edinger Lift St ation testing was performed on Friday May 9, 2008 between 7:00 and 9:00 a.m. when the wastewater flows were anticipated to be at its highest.

The flow rates determined during the field testing were compared to the readings at the existing flow meter at the Edinger Lift Station, which may be too low. The field testing consisted of measuring the time it takes to fill the wet well, every 0.5-foot increment between wet well levels of 2 feet to 5 feet. The time it takes each pump to lower the depth of wastewater in the wet well, every 0.5-foot increment between wet well levels of 5 feet to 2 feet was also measured.

The wastewater levels in the wet well are constricted because the trib utary sewer system will experience backflow conditions once the waste water level reaches an elevation of -8.50 feet amsl.

The average incoming flow rate was calculated as follows:

Time) ed(Accumulat
Volume) ed(AccumulatQ daccumulate =
Accumulated Volume = (L*W*H)*(7.48 gallons/cubic foot)
L = Length (7.5-feet)
W = Width (10.0-feet)
H = Height (0.5-feet)
Accumulated Time = Time to fill the wet well 3.0 feet (min)

During the testing period, the wet well filled from the 2-foot elevation to 5-foot elevation at a minimum time of 6 minutes and 15 seconds which corresponds to a flow rate of 269.3 gpm. The minimum time it took to raise the wet well level 0.5 feet was measured to be 59 second s, which corresponds to a flow rate of 285.3 gpm.

This value is used as the peak dry weather flow into the Edinger Lift Station.

The rate at which the flow is discharged is calculated in a similar manner; however, the flow into the wet well also needs to be accounted for. The flow rates were measured at every half foot increment to see how the

The discharge time was recorded at each 0.5 foot wet well depth increment. The flow reading from the lift station flow meter was also logged at most of the 0.5 f oot increments. The results show that the flow meters indicate flow rates lower than those measured by t he testing.

For the purposes of this study, the Edinger Lift Station is rated at the maximum output of 510 gpm.

Deficient Location No. 9

The 2003 Sewer Master Plan identified deficiencies in one (1) reach of 10-inch diameter sewer on Trinidad Lane south of Edinger Avenue; and seven (7) reaches of 10-inch diameter sewer on Edinger Avenue between Trinidad Lane to the west and Santa Barbara Lane to t he east. With the master plan calculated peak dry weather flows, the d/D’s exceed 0.70 for all eight (8) reaches, which is deficient according to the master plan criteria. The total length of these deficient reaches is 2,171 feet. The flow direction is from south to north and west to east. These deficient sewers are downstream of the Trinidad Lift Station (LS No. 29), which has two pumps with rated capacities of 250 gpm, and upstream of the Edinger Lift Station (LS No. 25).

The flow monitor was installed in Pipe 166 on Edinger Avenue west of Bimini Lane, upstream of the manhole between Pipes 167 and 166. It measures most, but not a ll, of the flows tributary to the most downstream reach of the deficient sewers.

The Pipe 194 data is missing the slope value in the Ma ster Plan. However, the value can be estimated as

0.002, which is representative of t he slopes for the nearby pipes. The 2003 Sewer Master Plan estimates existing average dry weather flows of about 169 gpm in Pipe 165 to 190 gpm in Pipe 174. The average dry weather flow from flow monitoring (157 gpm) in Pipe 166 is approximately 92 pe rcent of the Master Plan estimated existing average dry weather flow of 1 69 gpm in Pipe 166. The average dry weather flows estimated in the Master Plan are relatively similar to the average dry weather flows recorded by the flow monitors; however, the relationship between the peak dry weather flows is not as close. The 2003 Sewer Master Plan estimates existing peak dry weather flows of about 376 gpm in Pipe 165 to 419 gpm in Pipe 174.

The peak dry weather flow from flow monitoring (277 gpm) in Pipe 166 is approximately 74 percent of the Master Plan estimated existing peak dry weather flow of 376 gpm in Pipe 166. The discrepancy between the measured and estimated flows may be due to the hi gh coefficient used in the Master Plan peaking

K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis relationships. The Master Plan estimates only a 1.9 per cent increase in the peak dry weather flows with the ultimate development of the tributary area.

The 2003 Sewer Master Plan calculated similar flow values through Pipes 194, 165, 166, and 167. The peak dry weather flows from the Master Plan calculations we re exceeding the capacity of these pipes with both the existing and ultimate peak dry weather flows. The Master Plan also calculated the depth to diameter ratios at

0.72. The flow monitoring data shows that these four (4) pipes are flowing at a maximum depth to diameter ratio of 0.52. While this is deficient per the City’s criteria, it does not warrant replacement of the existing pipes for capacity. If the tributary land use is proposed to be c hanged significantly in the future, resulting in higher wastewater flows, then these reaches should be re-evaluated.

According to the 2003 Sewer Master Plan, the four (4) reaches along Edinger Avenue between Bimini Lane to the west and the Edinger Lift station to the east, exper ience higher flows than the upstream reaches. The average dry weather flows from the lift station are a c onservative estimate of the average dry weather flows through these four (4) reaches. The Master Plan calculated the average dry weather flow rates for Pipes 168, 169, 170, and 174 between 184 gpm to 190 gpm. The average dry weather flow from Flow Monitoring Site No. 11 (205 gpm) is approximately 8 percent higher than the Master Plan estimated average dry weather flow at Pipe 174 (190 gpm).

During the pump testing on Friday May 9, 2008, the ex isting peak dry weather flows were measured to be approximately 285 gpm at the Edinger Lift Station.

The Master Plan estimates only a 2.1 percent increase in the average dry weather flows with the ultimate dev elopment of the tributary area. Applying the same increase to the measured flows, the ultimate peak dr y weather flow would be 291 gpm. Based on a slope of

0.002, Manning’s n of 0.013 and the ultimate peak dry weather flow, the four (4) existing 10-inch sewers are flowing at a d/D of 0.59. While this calculated d/D is deficient per the City’s criteria, it does not necessarily warrant replacement of the existing pipes for capacity. If the tributary land use is proposed to be changed in the future, resulting in higher wastewater flows, then these reaches should be re-evaluated.

Deficient Location No. 8

The 2003 Sewer Master Plan identified capacity deficienc ies in ten (10) reaches of 10-inch diameter sewers located on Santa Barbara Lane and Mandalay Circle between the Edinger Lift Station (LS No. 25) and Humboldt Drive. With the master plan calculated peak dry weather flows, all ten (10) reaches were flowing full. The total length of these reaches is 1,964 feet.

In order to evaluate the effect of Edinger Lift Station (LS No. 25) flows on the do wnstream sewers, two flow monitors were initially installed on June 14, 2007. Two additional flow monitors were installed once the improvements to the Edinger Lift Stations were finalized.

On June 14, 2007, the first flow monitor was installe d in the downstream end of Pipe 202 at the manhole between Pipes 206 and 202 on Santa Barbara Lane and Sh orebreak Drive (FM Site No. 11). Pipe 202 is the first pipe downstream of the Edinger Lift Station force main.

The comparison of the initial flow monitoring dat a and the 2003 Sewer Master Plan results for the area tributary to the flow monitoring site is shown in Table 15.

Master Plan Data Data Flow Monitoring Data

The 2003 Sewer Master Plan estimated the existing and ultimate peak dry weather flows at 434 gpm and 443 gpm, respectively. During pump operations before t he improvements were implemented, the flow monitor recorded the peak dry weather flow at 520 gpm, which was significantly higher than both master plan values.

During the Edinger Lift Station testing on June 14, 2007, t he flow monitor recorded the peak dry weather flow at 900 gpm, which is significantly higher than all values.

The Master Plan also estimated that this pipe would flow at a depth to diameter ratio of 0.80 with the existing peak dry weather flows and full with the ultimate peak dry weather flows. With the normal pump operations during June 2007, the flow monitoring equipment recorded the maximum depth to diameter ratio at about 0.87 which verifies that this 10” diameter sewer does not m eet the existing criteria. When the Edinger Lift Station testing was performed, Site No 11 experienced full flow conditions.

The design flow for the Edinger Lift Station is ro ughly 400 gpm; however, the pumping tests performed on May 9, 2008 show that the actual pumping rate is as high as 510 gpm. The measured pumping rate is capable of conveying both the existing and ultimate peak dry weather flows, and this value (510 gpm) will be used to evaluate the downstream sewer capacities. Based on a slope of 0.002, and a Manning’s n of 0.013, the required pipe size would be 15-inch diameter.

Flow monitoring was performed at the downstream end of Pipe 232 at the manhole between Pipes 237 and 232 on Mandalay Circle north of Humboldt Drive (FM Si te No. 8). The flow monitoring was performed in June, 2007 to analyze the affect the Edinger Lift Station had on the downstream sewer system. However, the Edinger Lift Station capacity was recently increased, and additional flow monitoring was necessary to analyze the downstream system based on the new pump capacities . A flow monitor was installed at Site No. 8 in January, 2008. The comparison of the flow monitoring data and the 2003 Sewer Master Plan results is shown in Table 16. This table shows the flows at Site No . 8 before and after the improvements to the Edinger Lift Station (LS No. 25) were completed. For the purposes of this report, the downstream reaches will be analyzed with the most-recent flow monitoring data because it represents the existing flow conditions.

The 2003 Sewer Master Plan existing and ultimate peak dry weather flows exceed the capacities of the nine (9) reaches of sewers listed above. The existing pea k dry weather flows varied from 438 gpm to 494 gpm, with the ultimate peak dry weather flows approximatel y 3 percent higher. With the upgraded Edinger Lift Station in operation, Flow Monitoring Site No. 8 reco rded the peak dry weather flow as 500 gpm, which is similar to the Master Plan values. The Peak Dry weather flow (500 gpm) at flow monitoring Site No. 8 is less than the measured discharge at the Ed inger Lift Station, due to the attenuat ion of the flows in the upstream gravity system.

For the most part, the flow monitoring data at Site No. 8 consistently displays typical flow patterns during the three (3) weeks that the flow monitor collected data. However, on January 26, 2008, there was a power outage which shutdown both the Edinger Lift Station (#25 ) and the Saybrook Lift Station (#22). The power outage lasted between 5:45 P.M. to 7:10 P.M. As shown in Appendix C, Site 8 displays an abnormally high flow rate at 7:30. Once the power at the pump station was restored, the two (2) pumps were both automatically turned on to discharge the wastewater that accumulated in the wet well. This flow rate (656 cfs) at 7:30 illustrates the scenario when both pumps are running.

During normal operations, the flow monitor recorded full or near full levels between 7:00 A.M. and 10:30 A.M, which coincides with normal peak wastewater production periods. Although it does not appear that two (2) pumps are running simultaneously during this time, the pumps are required to operate more frequently since the wet well fills at a faster rate du ring the peak period. The detailed fl ow monitoring results show the daily depths rise to full or near full levels at Site No. 8 for 1 to 4 hour periods. Based on the slope of 0.002, Manning’s n of 0.013 and the flow monitoring maximum flow of 500 gpm, a minimum pipe diameter of 15 inches would be necessary to meet the City’s depth to di ameter design criteria of 0.67 for the nine (9) study reaches. The 15-inch pipe would also have the capaci ty to convey the measured flow rate of 656 cfs during the case when both pumps were in operation.

The maximum inflow into the Edinger Lift Station was measured to be approximately 285 gpm and the pumps are discharging roughly 500 gpm. To reduce the depth to diameter ratio in the ten (10) downstream sewers, the City may decrease the pump capacity from 500 gpm to 400 gpm. In doing so, approximately 37% of the ultimate PDWF will remain available for wet weather inflow and infiltration. By reducing the flow to 400 gpm,

SEWER SYSTEM CAPACITY ANALYSIS
1-21 City of Huntington Beach
K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis the downstream sewers are expected to flow at a depth to diameter ratio of approximately 0.744. While this is deficient according to the City’s standards, the sewers will no longer experience full flow conditions.

To evaluate the effects of the improvements to the Edinger Lift Station (LS No. 25), an additional flow monitor was installed between Site No. 8 and the Saybrook Lift Station (LS No. 22). The flow monitor was installed in Pipe 256, upstream of the manhole between Pipes 256 a nd 261. It measures nearly the entire flow tributary to the Saybrook Lift Station. The comparison between the flow monitoring data and the 2003 Sewer Master Plan results is shown in Table 17.

Like Site No. 8, the flow monitoring results at Site No. 12 are fairly typical, however, the site experienced high and low flows when the power outage left the Saybrook Lift Station (LS No. 22) and Edinger Lift Stations (LS No. 25) inoperable. As Shown in Appendix C, Site No . 12 experienced back water conditions at about 6:00 P.M. where the flow level reached the top of the pipe and t he flow rate is zero. Site 12 is just upstream of the Saybrook Lift Station; therefore, the flow accumulated in the pipe once the wet well had reached its maximum capacity. During the power outage, Site No. 8 did not experience these backwater conditions because it is further upstream. Once the power at the lift stati on was restored, the two (2) pumps were automatically turned on to discharge the wastewater that accumulated in the wet well during the power outage. This flow rate (771 cfs) at 7:30 illustrates the scenario when both pumps are running.

The 2003 Sewer Master Plan considered Pipes 239, 256, and 261 to be “Borderline conditions”, with ultimate average dry weather flows between 300 gpm and 368 gpm. During the master planning effort, “Borderline conditions” were the reaches that had calculated d/D values which were close the deficiency criteria d/D values, but were not determined “Deficient” by engineering judgment.

During normal dry weather conditions the flow monitoring shows that the average and peak dry weather flows are 247 gpm and 517 gpm respectively. The Sewer Master Plan peak dry weather flow (758 gpm) is larger than the flow monitoring peak dry weather flow (517 gpm) by a factor of 1.47. According to the flow monitoring data, this 12” sewer is flowing at a d/D of 0.58. While this is deficient per the City’s criteria, it does not warrant replacement of the existing pipes for capacity. If the tributary land use is proposed to be changed significantly in the future, resulting in higher wastewater flows, then these reaches should be re-evaluated.

Deficient Location No. 7

The 2003 Sewer Master Plan identified a capacity deficien cy in one (1) reach of 8-inch diameter sewer on Saybrook Lane between Heil Avenue to the north and Morning Star Drive on the south. With the master plan calculated peak dry weather flow, this reach is flowing fu ll. The total length is 290 feet, and the flow direction

K:\Huntington Beach\Huntington_Beach_Capacity_study Capacity Analysis is from north to south. This reach conveys the wastewater flow pumped by Saybrook Lift Station (LS No. 22), located on Saybrook Lane north of Heil Avenue.

The flow monitor was installed in the downstream en d of Pipe 2586, upstream of the manhole between Pipes 312 and 2586 at the intersection of Saybrook Lane and Mo rning Star Drive. It measures the entire flow tributary to the deficient sewer. The comparis on between the flow monitoring data and the 2003 Sewer Master Plan results is shown in Table 18.

Master Plan Data Data Flow Monitoring Data

Based upon information contained in Appendix D of the 2003 Sewer Master Plan, the existing peak dry weather flow is 652 gpm, and the ultimate peak dry weather flow is 760 gpm. The Master Plan calculated a depth to diameter ratio of 0.75 in this 12-inch pipe with the existing peak dry weather flows. The flow monitoring equipment recorded a peak dry weather flow of 642 gpm, which is nearly the firm capacity of the Saybrook Lift Station. The flow monitors recorded the maximum depth to diameter ratio at 0.59 which verifies that this 12” diameter sewer does not meet the City’s existing criteria.

The City anticipates that the Saybrook Lift Station will be replaced within the next 3 and 8 years. To reduce the length of time that the pumps are running, it is anticipated that the City will double the firm capacity of the pumps. Each pump’s existing design capacity is 413 gpm. The City recommends that the future design capacity of the downstream sewers will be 826 gpm. A minimum pipe diameter of 15 inches is needed to meet the City’s depth to diameter design criteria of 0.67. These reache s will require additional evaluation by the City.

The system downstream of this reach should also be evaluated for this planned increase in the flows.
